Related Vulnerabilities: CVE-2008-5077   CVE-2008-5077  

Synopsis

Important: openssl security update

Type/Severity

Security Advisory: Important

Topic

Updated OpenSSL packages that correct a security issue are now available
for Red Hat Enterprise Linux 2.1, 3, 4, and 5.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

Description

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

The Google security team discovered a flaw in the way OpenSSL checked the
verification of certificates. An attacker in control of a malicious server,
or able to effect a "man in the middle" attack, could present a malformed
SSL/TLS signature from a certificate chain to a vulnerable client and
bypass validation. (CVE-2008-5077)

All OpenSSL users should upgrade to these updated packages, which contain
backported patches to resolve these issues. For the update to take effect,
all running OpenSSL client applications must be restarted, or the system
rebooted.

Solution

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