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"
