GnuPG: Integer overflow vulnerability — GLSA 200608-08

GnuPG is vulnerable to an integer overflow that could lead to the execution of arbitrary code.

Affected Packages

app-crypt/gnupg on all architectures
Affected versions < 1.4.5
Unaffected versions >= 1.4.5

Background

The GNU Privacy Guard, GnuPG, is a free replacement for the PGP suite of cryptographic software.

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*"
