Werner Koch 824d88ac51 gpg: Prevent an invalid memory read using a garbled keyring. ...

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

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.
