Description
Evgeny Legerov discovered a vulnerability in GnuPG that when certain packets are handled an integer overflow may occur.
Impact
By sending a specially crafted email to a user running an affected version of GnuPG, a remote attacker could possibly execute arbitrary code with the permissions of the user running GnuPG.
Workaround
There is no known workaround at this time.
Resolution
All GnuPG users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose "=app-crypt/gnupg-1.4*"
