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:

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-crypt/gnupg-1.4.17"
