Synopsis
========
GnuPG is vulnerable to an integer overflow that could lead to the
execution of arbitrary code.
Background
==========
The GNU Privacy Guard, GnuPG, is a free replacement for the PGP suite
of cryptographic software.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-crypt/gnupg < 1.4.5 >= 1.4.5
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-1.4.5"
References
