RHSA-2010:0164 - Moderate: openssl097a security update
Synopsis
Moderate: openssl097a security update
Type/Severity
Security Advisory Moderate
Topic
Updated openssl097a packages that fix a security issue are 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.
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.
A flaw was found in the way the TLS/SSL (Transport Layer Security/Secure Sockets Layer) protocols handled session renegotiation. A man-in-the-middle attacker could use this flaw to prefix arbitrary plain text to a client's session (for example, an HTTPS connection to a website). This could force the server to process an attacker's request as if authenticated using the victim's credentials. This update addresses this flaw by implementing the TLS Renegotiation Indication Extension, as defined in RFC 5746. (CVE-2009-3555)
Refer to the following Knowledgebase article for additional details about this flaw: http://kbase.redhat.com/faq/docs/DOC-20491
All openssl097a 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 openssl097a library must be restarted, or the system rebooted.
Solution
Before applying this update, make sure all previously-released errata relevant to your system have been applied.
