Important: gnupg security update

Updated GnuPG packages that fix two security issues are now available.

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.

Tavis Ormandy discovered a stack overwrite flaw in the way GnuPG decrypts
messages. An attacker could create carefully crafted message that could cause
GnuPG to execute arbitrary code if a victim attempts to decrypt the message.
(CVE-2006-6235)

A heap based buffer overflow flaw was found in the way GnuPG constructs
messages to be written to the terminal during an interactive session. An
attacker could create a carefully crafted message which with user interaction
could cause GnuPG to execute arbitrary code with the permissions of the
user running GnuPG. (CVE-2006-6169)

All users of GnuPG are advised to upgrade to this updated package, which
contains a backported patch to correct these issues.

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
