1. Summary:
An updated gnupg2 package that fixes one security issue is now available for Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
2. Relevant releases/architectures:

3. Description:
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 use-after-free flaw was found in the way gpgsm, a Cryptographic Message Syntax (CMS) encryption and signing tool, handled X.509 certificates with a large number of Subject Alternate Names. A specially-crafted X.509 certificate could, when imported, cause gpgsm to crash or, possibly, execute arbitrary code. (CVE-2010-2547)
All gnupg2 users should upgrade to this updated package, which contains a backported patch to correct this issue.
4. Solution:
Before applying this update, make sure all previously-released errata relevant to your system have been applied.
