  tag_insight = "The GNU Privacy Guard (GnuPG or GPG) is a tool for encrypting data and
creating digital signatures, compliant with the proposed OpenPGP Internet
standard and the S/MIME standard.

A denial of service flaw was found in the way GnuPG parsed certain
compressed OpenPGP packets. An attacker could use this flaw to send
specially crafted input data to GnuPG, making GnuPG enter an infinite loop
when parsing data. (CVE-2013-4402)

It was found that importing a corrupted public key into a GnuPG keyring
database corrupted that keyring. An attacker could use this flaw to trick a
local user into importing a specially crafted public key into their keyring
database, causing the keyring to be corrupted and preventing its further
use. (CVE-2012-6085)

It was found that GnuPG did not properly interpret the key flags in a PGP
key packet. GPG could accept a key for uses not indicated by its holder.
(CVE-2013-4351)

Red Hat would like to thank Werner Koch for reporting the CVE-2013-4402
issue. Upstream acknowledges Taylor R Campbell as the original reporter.

All gnupg2 users are advised to upgrade to this updated package, which
contains backported patches to correct these issues.
