Serge Mister and Robert Zuccherato reports that the OpenPGP protocol
is vulnerable to a cryptographic attack when using symmetric
encryption in an automated way.
David Shaw reports about the impact :
This attack, while very significant from a cryptographic point of
view, is not generally effective in the real world. To be specific,
unless you have your OpenPGP program set up as part of an automated
system to accept encrypted messages, decrypt them, and then provide a
response to the submitter, then this does not affect you at all.
Note that the fix in GnuPG does note completely eliminate the
potential problem :
These patches disable a portion of the OpenPGP protocol that the
attack is exploiting. This change should not be user visible. With the
patch in place, this attack will not work using a public-key encrypted
message. It will still work using a passphrase-encrypted message.
