Red Hat Security Advisory: openssl security update Security Advisory secalert@redhat.com Red Hat Security Response Team RHSA-2012:0522 Final 1 1 2012-04-25T12:28:00Z Current version 2012-04-25T12:28:00Z 2012-04-25T12:28:00Z Red Hat rhsa-to-cvrf 1.0.1478 2012-05-01T14:47:03Z Updated openssl packages that fix one security issue are now available for Red Hat Enterprise Linux 3 and 4 Extended Life Cycle Support; Red Hat Enterprise Linux 5.3 Long Life; and Red Hat Enterprise Linux 5.6, 6.0 and 6.1 Extended Update Support. 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.
