Synopsis
========

A vulnerability in GnuPG can lead to a Denial of Service condition.

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 < 2.0.24 *>= 1.4.21
*>= 1.4.17
*>= 1.4.18
*>= 1.4.20
*>= 1.4.19
>= 2.0.24

Description
===========

GnuPG does not properly handle a specially crated compressed packet
resulting in an infinite loop.

Impact
======

A context-dependent attacker can cause a Denial of Service.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All GnuPG 2.0 users should upgrade to the latest version:

# emerge –sync
# emerge –ask –oneshot –verbose “>=app-crypt/gnupg-2.0.24”

All GnuPG 1.4 users should upgrade to the latest version:
