gpg: Fix segv due to NULL value stored as opaque MPI
* g10/build-packet.c (do_secret_key): Check for NULL return from
gcry_mpi_get_opaque.
* g10/keyid.c (hash_public_key): Ditto.

This is a backport of 76c8122adf from
master to the STABLE-BRANCH-1-4

On the STABLE-BRANCH-1-4, we may also want to patch g10/seckey-cert.c,
but that has not been done in this patch.

This fix extends commmit 0835d2f44e.

  gpg2 --export --no-default-keyring --keyring TESTDATA

With TESTDATA being below after unpacking.

Use inline functions to convert buffer data to scalars.
* include/host2net.h (buf16_to_ulong, buf16_to_uint): New.
(buf16_to_ushort, buf16_to_u16): New.
(buf32_to_size_t, buf32_to_ulong, buf32_to_uint, buf32_to_u32): New.

This fixes sign extension on shift problems.  Hanno Böck found a case
with an invalid read due to this problem.  To fix that almost all uses
of "<< 24" and "<< 8" are changed by this patch to use an inline
function from host2net.h.

04b0b050ff Add pubkey letters e and E for ECC.
This does not mean we have any kind of ECC support now.  It is merely
to avoid printing a question mark for the algorithm.

Trailing white space changes as usual.

merge_selfsigs_main, merge_selfsigs_subkey), keygen.c

longer.

options, and replace with no-op.

b96038387b * keyserver.c (keyserver_typemap): New. Map certain keyserver types to a

http and ftp to curl.

* build-packet.c (build_sig_subpkt): Only allow one preferred keyserver
subpacket at a time.

d49a7e1a7a * plaintext.c (handle_plaintext): Accept 'u' as a plaintext mode that
requires end of line conversion.  This is being considered for a UTF8 text
packet.  If this doesn't take place, no major harm done.  If it does take
place, we'll get a jump on starting the changeover.

* g10.c (main): --no-use-embedded-filename.

* build-packet.c (calc_plaintext, do_plaintext): Do not create illegal
(packet header indicates a size larger than the actual packet) encrypted
data packets when not compressing and using a filename longer than 255
characters.

* keyedit.c (no_primary_warning): Cleanup. (menu_expire): Don't give
primary warning for subkey expiration changes.  These cannot reorder
primaries.

David Shaw
4420275b83 * keygen.c (gen_elg, gen_dsa, gen_rsa, do_create, do_generate_keypair,
generate_subkeypair): New is_subkey argument to set whether a generated
key is a subkey.  Do not overload the ret_sk.  This is some early cleanup
to do backsigs for signing subkeys.

* keygen.c (write_keybinding, do_generate_keypair, generate_subkeypair):
Keep track of the unprotected subkey secret key so we can make a backsig
with it.

* keygen.c (make_backsig): New function to add a backsig to a binding sig
of signing subkeys.  Currently disabled. (write_keybinding): Call it here,
for signing subkeys only.

* sign.c (make_keysig_packet): Allow generating 0x19 signatures (same as
0x18 or 0x28, but used for backsigs).

* packet.h, build-packet.c (build_sig_subpkt): Add new SIGSUBPKT_SIGNATURE
type for embedded signatures.

56a6945261 * build-packet.c (write_header2): Remove call to start old gpg partial
length mode and change all callers. (do_plaintext): Turn off partial
length encoding now that we're done writing the packet. (do_comment,
do_user_id): Try for a headerlen of 2 since that's the smallest and most
likely encoding for these packets.

* parse-packet.c (parse): Remove call to start old gpg partial length
mode.

2ecb28c51b * build-packet.c (do_user_id): Do not force a header for attribute packets

CTBs yet.

David Shaw
95d05215c3 * build-packet.c (write_header2): If a suggested header length is provided
along with a zero length, interpret this as an actual zero length packet
and not as an indeterminate length packet. (do_comment, do_user_id): Use
it here as these packets might be naturally zero length.

* parse-packet.c (parse): Show packet type when failing due to an
indeterminate length packet.

* misc.c (parse_options): Only provide args for the true (i.e. not
"no-xxx") form of options.

7847eae02c * build-packet.c (write_fake_data, do_secret_key), seckey-cert.c

opt.force_ownertrust.

db5ab5e730 * packet.h, build-packet.c (hash_public_key): Remove function ...
* keydb.h, keyid.c (hash_public_key, do_fingerprint_md): ... and make a
new one here that shares code with the fingerprint calculations.  This
removes some duplicated functionality, and is also around 14% faster.
(Every bit helps).

* import.c (import_one): No longer need the Elgamal import warning.

* getkey.c (get_pubkey_fast): This one is sort of obscure. get_pubkey_fast
returns the primary key when requesting a subkey, so if a user has a key
signed by a subkey (we don't do this, but used to), AND that key is not
self-signed, AND the algorithm of the subkey in question is not present in
GnuPG, AND the algorithm of the primary key that owns the subkey in
question is present in GnuPG, then we will try and verify the subkey
signature using the primary key algorithm and hit a BUG().  The fix is to
not return a hit if the keyid is not the primary.  All other users of
get_pubkey_fast already expect a primary only.

preferred keyserver to specified (or all) user IDs.

* build-packet.c (build_sig_subpkt): Set preferred keyserver flag while
building a preferred keyserver subpacket.

3afe991bb8 * packet.h, build-packet.c (build_sig_subpkt), export.c
(do_export_stream), import.c (remove_bad_stuff, import), parse-packet.c
(dump_sig_subpkt, parse_one_sig_subpkt): Remove vestigal code for the old
sig cache subpacket.  This wasn't completely harmless as it caused
subpacket 101 to disappear on import and export.

* options.h, armor.c, cipher.c, g10.c, keyedit.c, pkclist.c, sign.c,
encode.c, getkey.c, revoke.c: The current flags for different levels of
PGP-ness are massively complex.  This is step one in simplifying them. No
functional change yet, just use a macro to check for compliance level.

* sign.c (sign_file): Fix bug that causes spurious compression preference
warning.

* sign.c (clearsign_file): Fix bug that prevents proper warning message
from appearing when clearsigning in --pgp2 mode with a non-v3 RSA key.

* main.h, misc.c (compliance_option_string, compliance_string,
compliance_failure), pkclist.c (build_pk_list), sign.c (sign_file,
clearsign_file), encode.c (encode_crypt, write_pubkey_enc_from_list): New
functions to put the "this message may not be usable...." warning in one
place.

* options.h, g10.c (main): Part two of the simplification.  Use a single
enum to indicate what we are compliant to (1991, 2440, PGPx, etc.)

* g10.c (main): Show errors for failure in export, send-keys, recv-keys,
and refresh-keys.

* options.h, g10.c (main): Give algorithm warnings for algorithms chosen
against the --pgpX and --openpgp rules.

* keydb.h, pkclist.c (algo_available): Make TIGER192 invalid in --openpgp
mode.

* sign.c (sign_file), pkclist.c (algo_available): Allow passing a hint of
0.

1fc1d26083 * build-packet.c (build_sig_subpkt): Comments.
* exec.c (exec_write): Cast NULL to void* to properly terminate varargs
list.

* keyedit.c (show_key_with_all_names): Just for safety, catch an invalid
pk algorithm.

* sign.c (make_keysig_packet): Crucial that the call to mksubpkt comes
LAST before the calls to finalize the sig as that makes it possible for
the mksubpkt function to get a reliable pointer to the subpacket area.

* pkclist.c (do_we_trust_pre): If an untrusted key was chosen by a
particular user ID, use that ID as the one to ask about when prompting
whether to use the key anyway. (build_pk_list): Similar change here when
adding keys to the recipient list.

* trustdb.c (update_validity): Fix bug that prevented more than one
validity record per trust record. (get_validity): When retrieving validity
for a (user) supplied user ID, return the validity for that user ID only,
and do not fall back to the general key validity. (validate_one_keyblock):
Some commentary on whether non-self-signed user IDs belong in the web of
trust (arguably, they do).

874214d0a0 * import.c (import_revoke_cert): Remove ultimate trust when revoking an

* keyedit.c (sign_uids): Allow replacing expired signatures. Allow
duplicate signatures with --expert.

* pkclist.c (check_signatures_trust): Don't display a null fingerprint
when checking a signature with --always-trust enabled.

* filter.h (progress_filter_context_t), progress.c (handle_progress),
plaintext.c (ask_for_detached_datafile, hash_datafiles): Fix compiler
warnings.  Make "what" constant.

* build-packet.c (do_plaintext): Do not create invalid literal packets
with >255-byte names.

1aec20776c * main.h, keyedit.c, keygen.c: Back out previous (2002-12-01) change.
Minimal isn't always best.

* sign.c (update_keysig_packet): Use the current time rather then a
modification of the original signature time.  Make sure that this doesn't
cause a time warp.

* keygen.c (keygen_add_key_expire): Properly handle a key expiration date
in the past (use a duration of 0).

* keyedit.c (menu_expire): Use update_keysig_packet so any sig subpackets
are maintained during the update.

* build-packet.c (build_sig_subpkt): Mark sig expired or unexpired when
the sig expiration subpacket is added. (build_sig_subpkt_from_sig): Handle
making an expiration subpacket from a sig that has already expired (use a
duration of 0).

* packet.h, sign.c (update_keysig_packet), keyedit.c
(menu_set_primary_uid, menu_set_preferences): Add ability to issue 0x18
subkey binding sigs to update_keysig_packet and change all callers.

David Shaw
ae1d1288ee * keyedit.c (sign_mk_attrib, trustsig_prompt, sign_uids, keyedit_menu):
Prompt for and create a trust signature with "tsign".  This is functional,
but needs better UI text.

* build-packet.c (build_sig_subpkt): Able to build trust and regexp
subpackets.

* pkclist.c (do_edit_ownertrust): Comment.
2002-11-03 12:46:52 +00:00
David Shaw
20c99d180a * build-packet.c (do_plaintext), encode.c (encode_sesskey, encode_simple,

of memset() to wipe sensitive memory as the memset() might be optimized
away.

(checksum_mpi): Ditto.
(checksum_mpi_counted_nbits): Removed and replaced all calls
with checksum_mpi.
* parse-packet.c (read_protected_v3_mpi): New.
(parse_key): Use it here to store it as an opaque MPI.
* seckey-cert.c (do_check): Changed the v3 unprotection to the new
why to store these keys.

Werner Koch
5dfd5a6dac * pkclist.c (do_we_trust_pre): Changed the wording of a warning.
* encode.c (encode_simple,encode_crypt): Use new style CTB for
compressssed packets when using MDC.  We need to do this so that
concatenated messages are properly decrypted.  Old style
compression assumes that it is the last packet; given that we
can't determine the length in advance, the uncompressor does not
know where to start.  Actually we should use the new CTB always
but this would break PGP 2 compatibility.
* parse-packet.c (parse): Special treatment for new style CTB
compressed packets.

* build-packet.c (do_mdc): Removed. Was not used.
(do_encrypted_mdc): Count the version number and the MDC packet.

"include-sensitive-revkeys".

* options.h, hkp.c (hkp_export), keyserver.c (parse_keyserver_options,
keyserver_spawn): try passing unknown keyserver options to export options,
and if successful, use them when doing a keyserver --send-key.

* build-packet.c (build_sig_subpkt): We do not generate
SIGSUBPKT_PRIV_VERIFY_CACHE anymore.
