=====================================================================

1. Summary:

Updated openssl, openssl097a, and openssl098e packages that fix one
security issue are now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having
important 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.

3. Description:

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3)
and Transport Layer Security (TLS v1) protocols, as well as a
full-strength, general purpose cryptography library.

Multiple numeric conversion errors, leading to a buffer overflow, were
found in the way OpenSSL parsed ASN.1 (Abstract Syntax Notation One) data
from BIO (OpenSSL's I/O abstraction) inputs. Specially-crafted DER
(Distinguished Encoding Rules) encoded data read from a file or other BIO
input could cause an application using the OpenSSL library to crash or,
potentially, execute arbitrary code. (CVE-2012-2110)

All OpenSSL users should upgrade to these updated packages, which contain
a backported patch to resolve this issue. For the update to take effect,
all services linked to the OpenSSL library must be restarted, or the system
rebooted.

4. Solution:

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

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258

5. Bugs fixed (http://bugzilla.redhat.com/):

814185 - CVE-2012-2110 openssl: asn1_d2i_read_bio integer errors leading to
buffer overflow
