Text from Security Focus:


GnuPG is prone to a remote buffer-overflow vulnerability because it fails to
properly bounds-check user-supplied input before copying it to an insufficiently
sized memory buffer.

This issue may allow remote attackers to execute arbitrary machine code in the
context of the affected application, but this has not been confirmed.

GnuPG version 1.4.4 is vulnerable to this issue; previous versions may also be

The following Perl command demonstrates this issue by crashing the affected

perl -e 'print "\xfd\xff\xff\xff\xff\xfe"'| /var/gnupg/bin/gpg --no-armor


Comment 1 Nalin Dahyabhai 2006-08-01 18:45:20 UTC
An update to 1.4.5 hould show up in Raw Hide tomorrow.  Packages are also pushed
to FC4/FC5 testing, and will probably be moved to final status tomorrow as well,
at which point we'll close this bug.
