Oracle Linux 5 : gnupg (ELSA-2007-0107)

Synopsis :

The remote Oracle Linux host is missing a security update.

Description :

From Red Hat Security Advisory 2007:0107 :

Updated GnuPG packages that fix a security issue are now available for
Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

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.
