RHEL 5 / 6 : openssl (RHSA-2012:0518)

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

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.

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.
