cfbe6ba9cf agent: RSA signature verification by gpg-agent.
* g10/sign.c (do_sign): Let verify signature by gpg-agent.
* agent/pksign.c (agent_pksign_do): Call gcry_pk_verify for RSA.

--

RSA signature verification should be done to prevent attacks against
RSA CRT implementations and not to return invalid signature to
adversary.  Newer libgcrypt does so.  For older libgcrypt and
smartcards, gpg-agent does signature verification.

gpg: Report a conflict between honor-keyserver-url and TOR.
* g10/call-dirmngr.c (create_context): Send option and print a verbose
error.
--

It is in general a bad idea to use honor-keyserver-url but if Dirmngr
is running in TOR mode we should not allow this option at all.  We let
Dirmngr know about the use of this option and let Dirmngr tell use
whether TOR mode is active so that we can print a hint to disable that
keyserver option.

A future extension in gpgconf may disable that option directly but a
user may still override that and thus we better check.

--
Signed-off-by: Neal H. Walfield <neal@g10code.com>.

We currently don't skip keys if the search mode is
KEYDB_SEARCH_MODE_FIRST.  Since we change KEYDB_SEARCH_MODE_FIRST to
KEYDB_SEARCH_MODE_NEXT (to avoid a reset), it only makes sense to have
the same semantics for KEYDB_SEARCH_MODE_NEXT.

third parameter to be the index of the user id packet in the keyblock

--
Signed-off-by: Neal H. Walfield <neal@g10code.com>.

The keybox code doesn't work directly with keyblocks.  As such, the
matched user packet is not readily available to pass to
DESC[n].SKIPFNC.  But, we do know the index of the user id packet that
matched.  Thus, pass that instead.  If the skip function needs the
user id packet, it can use the key id to look up the key block and
find the appropriate packet.

Calling exit from an exit handler is undefined behaviour.  It works on
Linux but other systems will hit an endless loop.  That is indeed
unfortunate but we can't do anything about it.  Calling _exit() would
be possible but that may lead to other problems.  Thus we change to
call a custom exit function :-(.

Using "make check verbose=1" is supported by tests/openpgp and thus
we add the same mechanism here.

Commit e0873a33 started tracking whether key ids where definitely in

change (however, e0873a33 contains two separate changes and this only

What we do here is to keep track of key searches by long keyids (as
stored in all signatures) so that we do not need to scan the keybox
again after we already found that this keyid will result in
not-found.  As soon as we change gpg to run as a co-process we should
store this table per session because other instances of gpg may have
updated the keybox without us knowing.

On a test ring with

  gpg: 94721 good signatures
  gpg: 6831 bad signatures
  gpg: 150703 signatures not checked due to missing keys
  gpg: 5 signatures not checked due to errors

              Try to be as quiet as possible.

While the mentions about the stale trustdb information are edifying,
they aren't necessary, and shouldn't be emitted when the user requests
--quiet.

--

Note that although PKA is now always build, it will only work if
support for looking up via DNS has not been disabled.

The new PKA only works with the IPGP DNS certtype and shall be used
only to retrieve the fingerprint and optional the key for the first
time.  Due to the security problems with DNSSEC the former assumption
to validate the key using DNSSEC is not anymore justified.  Instead an
additional layer (e.g. Trust-On-First-Use) needs to be implemented to
track change to the key.  Having a solid way of getting a key matching
a mail address is however a must have.

More work needs to go into a redefinition of the --verify-options
pka-lookups and pka-trust-increase.  The auto-key-locate mechanism
should also be able to continue key fetching with another methods once
the fingerprint has been retrieved with PKA.

  Needed for unattended key edits with --status-fd, because since 2.1
  status prompts are preceded by es_fflush (in cpr.c:do_get_from_fd)
  not fflush(3), so the standard output may not be flushed before each
  prompt. (Which breaks scripts using select(2) to multiplex between
  the standard and status outputs.)

His patch only affected print_and_check_one_sig_colon() but there are
many more places where stdio and estream are mixed.  This patch now
replaces most of them in g10/.  At some places stdio is still used,
but that is local to a function and should not have side effects.

* g10/keyring.c (keyring_get_keyblock): Whitelist allowed packet
types.
* g10/keydb.c (parse_keyblock_image): Ditto.
--

The keyring DB code did not reject packets which don't belong into a
keyring.  If for example the keyblock contains a literal data packet
it is expected that the processing code stops at the data packet and
reads from the input stream which is referenced from the data packets.
Obviously the keyring processing code does not and cannot do that.
However, when exporting this messes up the IOBUF and leads to an
invalid read of sizeof (int).

We now skip all packets which are not allowed in a keyring.

Without that it is possible to force gpg to allocate large amounts of
memory by using a bad encoded MPI.  This would be an too easy DoS.
Another way to mitigate would be to change the MPI read function to
allocate memory dynamically while reading the MPI.  However, that
complicates and possibly slows down the code.  A too large key packet
is in any case a sign for broken data and thus gpg should not use it.

Thanks.

This bug can't be exploited: Only if the announced length of the

would be done.  The compared data is followed by the actual signature
and thus it is highly likely that not even read of unallocated memory

--

Allowing to use the abbreviated form for detached signatures is a long
standing bug which has only been noticed by the public with the
release of 2.1.0.  :-(

What we do is to remove the ability to check detached signature in
--batch using the one file abbreviated mode.  This should exhibit
problems in scripts which use this insecure practice.  We also print a
warning if a matching data file exists but was not considered because
the detached signature was actually a standard signature:

  gpgv: Good signature from "Werner Koch (dist sig)"
  gpgv: WARNING: not a detached signature; \
  file 'gnupg-2.1.0.tar.bz2' was NOT verified!

We can only print a warning because it is possible that a standard
signature is indeed to be verified but by coincidence a file with a
matching name is stored alongside the standard signature.

gnulib has always been a cause of trouble in GnuPG because we used
only a very few functions and the complex include machinery of gnulib
is quite complex and the cause for many build problems for example on
OS X.  This is not gnulib's fault but due to our limited use of gnulib
and that we only rarely update the gnulib code to avoid regressions.

In part two we will address the functions

 mkdtemp
 setenv
 unsetenv
 strpbrk

which may bot be implemented on all platforms.  They are not required
on a libc based system.

v3 keys are deprecated for about 15 years and due the severe
weaknesses of MD5 it does not make any sense to keep code around to
use these old and broken keys.  Users who need to decrypt old messages
should use gpg 1.4 and best re-encrypt them to modern standards.
verification of old (i.e. PGP2) created signatures is thus also not
anymore possible but such signatures have no values anyway - MD5 is
just too broken.

We have also kept support for v3 signatures until now.  With the
removal of support for v3 keys it is questionable whether it makes any
sense to keep support for v3-signatures.  What we do now is to keep
support for verification of v3-signatures but we force the use of
v4-signatures.  The latter makes the --pgp6 and --pgp7 switch a bit
obsolete because those PGP versions require v3-signatures for
messages.  These versions of PGP are also really old and not anymore
maintained so they have not received any bug fixes and should not be
used anyway.

We now cache the userids using the fingerprint.  This allows to print
the correct user id for keys with a duplicated key id.  We should
eventually start to retire the use of all the old keyid based
functions.  However, at some places we only have the keyid and thus
some of them will need to be kept (maybe changed with an indication to
show that more than several user ids are matching).

This is a cherry-pick of 534e2876acc05f9f8d9b54c18511fe768d77dfb5 from
STABLE-BRANCH-1-4 against master

Some older implementations built and used RSA keys up to 16Kib, but
the larger secret keys now fail when used by more recent GnuPG, due to
secure memory limitations.

Building with ./configure --enable-large-secmem will make gpg
capable of working with those secret keys, as well as permitting the
use of a new gpg option --enable-large-rsa, which let gpg generate RSA
keys up to 8Kib when used with --batch --gen-key.

The problem was reported by dkg on gnupg-devel (2014-10-07):

  I just discovered a new problem, though, which will affect people on
  systems that have gpg and gpg2 coinstalled:

   0) create a new keyring with gpg2, and use it exclusively with gpg2
  for a while.
   1) somehow (accidentally?) use gpg (1.4.x) again -- this creates
  ~/.gnupg/pubring.gpg
   2) future runs of gpg2 now only look at pubring.gpg and ignore
  pubring.kbx -- the keys you had accumulated in the keybox are no
  longer listed in the output of gpg2 --list-keys

Note that gpgsm has always used pubring.kbx and thus this file might
already be there but without gpg ever inserted a key.  The new flag in
the KBX header gives us an indication whether a KBX file has ever been
written by gpg >= 2.1.  If that is the case we will use it instead of
the default pubring.gpg.

In the course of building GnuPG 2.1.0 beta864 on debian, i found that
several of the installed executables were linked to libraries that
they did not need to be linked to, which would cause unnecessary
package dependencies at runtime.

The changeset here removes these unnecessary libraries from linking.

Something similar could possibly also be done by passing --as-needed
to the linker, but trimming the depenencies seems more parsimonious.

In gpg2, the following options are only relevant for scdaemon:

 reader-port
 ctapi-driver
 pcsc-driver
 disable-ccid

but in gpg1, they are options for gpg itself.

Some users of gpg1 might have these options in their
~/.gnupg/gpg.conf, which causes gpg2 to fail hard if it reads that
config file.

gpg2 should not fail hard, though giving a warning (and suggesting a
move to scdaemon.conf) seems OK.

This patch does *not* reintroduce any documentation for these options
in gpg.texi, even to indicate that they are "dummy" options, since
scdaemon.texi contains the appropriate documentation.

This patch adds two features:

1. The key for the last passphrase successfully used for unprotecting
a key is stored away.  On a cache miss the stored away passphrase is
tried as well.  This helps for the common GPG use case of having a
signing and encryption (sub)key with the same passphrase.  See the
code for more comments.

2. The now auto-generated revocation certificate does not anymore
popup a passphrase prompt.  Thus for standard key generation the
passphrase needs to be given only once (well, two with the
confirmation).

* g10/parse-packet.c (parse_attribute): Avoid xmalloc failure and cap
size of packet.
--

Tavis Ormandy reported a fatal error for attribute packets with a zero
length payload.  This is due to a check in Libgcrypt's xmalloc which
rejects a malloc(0) instead of silently allocating 1 byte.  The fix is
obvious.

In addition we cap the size of attribute packets similar to what we do
with user id packets.  OpenPGP keys are not the proper way to store
movies.

It was possible to create 16k RSA keys in batch mode. In addition to the
silliness of such keys, they have the major drawback that under GnuPG
and Libgcrypt, with their limited amount of specially secured memory
areas, the use of such keys may lead to an "out of secure memory"
condition.

* g10/compress.c (do_uncompress): Limit the number of extra FF bytes.
--

A packet like (a3 01 5b ff) leads to an infinite loop.  Using
--max-output won't help if it is a partial packet.  This patch
actually fixes a regression introduced on 1999-05-31 (c34c6769).
Actually it would be sufficient to stuff just one extra 0xff byte.
Given that this problem popped up only after 15 years, I feel safer to
allow for a very few FF bytes.

Thanks to Olivier Levillain and Florian Maury for their detailed
report.

* common/xmalloc.c (xmalloc, xcalloc): Take extra precaution not to

The problem did not occur in 1.x because over there the xmalloc makes
sure to allocate at least one byte.  With 2.x for most calls the
xmalloc of Libgcrypt is used and Libgcrypt returns an error insteead
of silent allocating a byte.  Thus gpg 2.x bailed out with an
"Fatal: out of core while allocating 0 bytes".

The extra code in xmalloc.c is for more robustness for the other
xmalloc calls.

By modifying a keyserver or a DNS record to send a secret key, an
attacker could trick a user into signing using a different key and
user id.  The trust model should protect against such rogue keys but
we better make sure that secret keys are never received from remote
sources.

For ECC it seems to be better to show the name of the curve and not
just the size of the prime field.  The curve name does not anymore fit
into the "<size><letter>" descriptor (e.g. "2048R") and a fixed length
format does not work either.  Thus the new format uses

   "rsa2048"    - RSA with 2048 bit
   "elg1024"    - Elgamal with 1024 bit
   "ed25519"    - ECC using the curve Ed25519.
   "E_1.2.3.4"  - ECC using the unsupported curve with OID "1.2.3.4".

unless --legacy-list-mode is given.  In does not anymore line up
nicely in columns thus I expect further changes to this new format.

This patch separates Libgcrypt and OpenPGP public key algorithms ids
and in most cases completely removes the Libgcrypt ones.  This is
useful because for Libgcrypt we specify the algorithm in the
S-expressions and the public key ids are not anymore needed.

This patch also adds some support for PUBKEY_ALGO_EDDSA which will
eventually be used instead of merging EdDSA with ECDSA.  As of now an
experimental algorithm id is used but the plan is to write an I-D so
that we can get a new id from the IETF.  Note that EdDSA (Ed25519)
does not yet work and that more changes are required.

The ECC support is still broken right now.  Needs to be fixed.

This feature can be used to return the session key for just a part of

decrypting that incomplete part and while ignoring all the errors
break out the session key.  The session key may then be used on the
server to decrypt the entire file without the need to have the private
key on the server.

This is a more general fix for the nested compression packet bug.  In
particular this helps g10/import.c:read_block to stop pushing
compression filters onto an iobuf stream.  This patch also reduces the
number of error messages for the non-import case.

--

With the gpg-agent taking care of the secret keys, the user needs to
migrate existing keys from secring.gpg to the agent.  This and also
the standard import of secret keys required the user to unprotect the
secret keys first, so that gpg-agent was able to re-protected them
using its own scheme.  With many secret keys this is quite some
usability hurdle.  In particular if a passphrase is not instantly
available.

To make this migration smoother, this patch implements an unattended
key import/migration which delays the conversion to the gpg-agent
format until the key is actually used.  For example:

   gpg2 --batch --import mysecretkey.gpg

works without any user interaction due to the use of --batch.  Now if
a key is used (e.g. "gpg2 -su USERID_FROM_MYSECRETKEY foo"), gpg-agent
has to ask for the passphrase anyway, converts the key from the
openpgp format to the internal format, signs, re-encrypts the key and
tries to store it in the gpg-agent format to the disk.  The next time,
the internal format of the key is used.

This patch has only been tested with the old demo keys, more tests
with other protection formats and no protection are needed.

be used.  This better reflects common sense.

This new features allows to use gpg without a Pinentry.  As a
prerequisite the agent must be configured to allow the loopback
pinentry mode (option --allow-loopback-pinentry).  For example

  gpg2 --pinentry-mode=loopback FILE.gpg

may be used to decrypt FILE.gpg while entering the passphrase on the
tty.  If batch is used, --passphrase et al. may be used, if
--command-fd is used, the passphrase may be provided by another
process.  Note that there are no try-again prompts in case of a bad
passphrase.

--

Gpg uses the key database at several places without a central
coordination.  This leads to several scans of the keybox for the same
key.  To improve that we now use a simple cache to store a retrieved
keyblock in certain cases.  In theory this caching could also be done
for old keyrings, but it is a bit more work and questionable whether
it is needed; the keybox scheme is anyway much faster than keyrings.

Using a keybox with 20000 384 bit ECDSA/ECHD keypairs and a 252 byte
sample text we get these values for encrypt and decrypt operations on
an Core i5 4*3.33Ghz system.  The option --trust-model=always is used.
Times are given in milliseconds wall time.

|           | enc | dec | dec,q |
|-----------+-----+-----+-------|
| key 1     |  48 |  96 |    70 |
| key 10000 |  60 |  98 |    80 |
| key 20000 |  69 | 106 |    88 |
| 10 keys   | 540 | 290 |    70 |

The 10 keys test uses a mix of keys, the first one is used for
decryption but all keys are looked up so that information about are
printed.  The last column gives decryption results w/o information
printing (--quiet).

The keybox is always scanned sequentially without using any index.  By
adding an index to the keybox it will be possible to further reduce
the time required for keys stored to the end of the file.

Import and key listing does now work with the keybox format.  It is

Increasing the maximum allowed length for a keyblock was required due
to a 700k keyblock which inhibited kbxutil to list the file.
kbxutil's option name --import-openpgp is not quite appropriate
because it only creates KBX blobs from OpenPGP data.

096e7457ec Change all quotes in strings and comments to the new GNU standard.
The asymmetric quotes used by GNU in the past (`...') don't render
nicely on modern systems.  We now use two \x27 characters ('...').

The proper solution would be to use the correct Unicode symmetric
quotes here.  However this has the disadvantage that the system
requires Unicode support.  We don't want that today.  If Unicode is
available a generated po file can be used to output proper quotes.  A
simple sed script like the one used for en@quote is sufficient to
change them.

The changes have been done by applying

  sed -i "s/\`\([^'\`]*\)'/'\1'/g"

to most files and fixing obvious problems by hand.  The msgid strings in
the po files were fixed with a similar command.

--

To keep the number of actually used algorithms low, we want to support
IDEA only in a basically read-only way (unless --pgp2 is used during
key generation).  It does not make sense to suggest the use of this
old 64 bit blocksize algorithm.  However, there is old data available
where it might be helpful to have IDEA available.

* g10/misc.c (pubkey_get_npkey, pubkey_get_nskey)
(pubkey_get_nsig, pubkey_get_nenc): Map all RSA algo ids to
GCRY_PK_RSA.
--

The problem is that Libgcrypt has no more support for the alternate
RSA ids and thus if asking for the number of parameters, they will
return zero.  Now, this leads to packing the key parameters into an
opaque MPI but because the algorithm id is actually known to GPG, it
assumes valid RSA parameters.

An example key with RSA_S is 0x5434509D.

37228cfa05 Allow generation of card keys up to 4096 bit.
This patch implementes a chunk mode to pass the key parameters from
scdaemon to gpg.  This allows to pass arbitrary long key paremeters;
it is used for keys larger than 3072 bit.

Note: the card key generation in gpg is currently broken.  The keys
are generated but it is not possible to create the self-signature
because at that time the gpg-agent does not yet know about the new
keys and thus can't divert the sign request to the card.  We either
need to run the learn command right after calling agent_scd_genkey or
implement a way to sign using the currently inserted card.  Another
option would be to get rid of agent_scd_genkey and implement the
feature directly in agent_genkey.

4206a2bd48 Detect premature EOF while parsing corrupted key packets.
This helps in the case of an unknown key algorithm with a corrupted
packet which claims a longer packet length.  This used to allocate the
announced packet length and then tried to fill it up without detecting
an EOF, thus taking quite some time.  IT is easy to fix, thus we do
it.  However, there are many other ways to force gpg to use large
amount of resources; thus as before it is strongly suggested that the
sysadm uses ulimit do assign suitable resource limits to the gpg
process.  Suggested by Timo Schulz.

328a642aa5 Fixed the ECC interface to Libgcrypt to be ABI compatible with the previous version.
Quite some changes were needed but in the end we have less code than
before.  Instead of trying to do everything with MPIs and pass them
back and forth between Libgcrypt and GnuPG, we know use the
S-expression based interface and make heavy use of our opaque MPI
feature.

Encryption, decryption, signing and verification work with
self-generared keys.

Import and export does not yet work; thus it was not possible to check

ECC code more similar to the rest of our code.

It builds but many sefltests still fail.  Need to fix that before
using it with an ECDH enabled libgcrypt.

   gpg2 --list-packets ~/.gnupg/pubring.gpg
   gpg2 --list-packets <private key from http://sites.google.com/site/brainhub/pgpecckeys>

ECDH doesn't work yet as the code must be re-written to adjust for gpg-agent refactoring.

pick something that isn't scored first choice).

* pkclist.c (select_algo_from_prefs): Slightly improve the handling of
MD5 in preference lists.  Instead of replacing MD5 with SHA-1, just
remove MD5 from the list altogether, and let the next-highest ranked
algorithm be chosen.
