Ubuntu GnuPG could be made to hang if it processed a specially crafted message.
Ubuntu Security Notice USN-2258-1
June 26, 2014

gnupg, gnupg2 vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.04 LTS
- Ubuntu 13.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS


GnuPG could be made to hang if it processed a specially crafted message.

Software Description:
- gnupg: GNU privacy guard - a free PGP replacement
- gnupg2: GNU privacy guard - a free PGP replacement


Jean-René Reinhard, Olivier Levillain and Florian Maury discovered that
GnuPG incorrectly handled certain OpenPGP messages. If a user or automated
system were tricked into processing a specially-crafted message, GnuPG
could consume resources, resulting in a denial of service.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 14.04 LTS:
  gnupg                           1.4.16-1ubuntu2.1
  gnupg2                          2.0.22-3ubuntu1.1

Ubuntu 13.10:
  gnupg                           1.4.14-1ubuntu2.2
  gnupg2                          2.0.20-1ubuntu3.1

Ubuntu 12.04 LTS:
  gnupg                           1.4.11-3ubuntu2.6
  gnupg2                          2.0.17-2ubuntu2.12.04.4

Ubuntu 10.04 LTS:
  gnupg                           1.4.10-2ubuntu1.6
  gnupg2                          2.0.14-1ubuntu1.7

In general, a standard system update will make all the necessary changes.
