"From Red Hat Security Advisory 2006:0615 :

Updated GnuPG packages that fix a security issue is now available.

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

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

An integer overflow flaw was found in GnuPG. An attacker could create
a carefully crafted message packet with a large length that could
cause GnuPG to crash or possibly overwrite memory when opened.
(CVE-2006-3746)

All users of GnuPG are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue."
