gnupg security update

CentOS Errata and Security Advisory CESA-2007:0106-01

GnuPG is a utility for encrypting data and creating digital signatures.

Gerardo Richarte discovered that a number of applications that make use of
GnuPG are prone to a vulnerability involving incorrect verification of
signatures and encryption. An attacker could add arbitrary content to a
signed message in such a way that a receiver of the message would not be
able to distinguish between the properly signed parts of a message and the
forged, unsigned, parts. (CVE-2007-1263)

Whilst this is not a vulnerability in GnuPG itself, the GnuPG team have
produced a patch to protect against messages with multiple plaintext
packets. Users should update to these erratum packages which contain the
backported patch for this issue.

Red Hat would like to thank Core Security Technologies for reporting this
issue.
