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

Summary:

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

Details:

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:

package versions:

gnupg2 2.0.22-3ubuntu1.1
