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

high Nessus Plugin ID 58869

Language:

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.

Solution

Update the affected packages.
