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.
