Summary

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.
An uninitialized variable use flaw was found in OpenSSL. This flaw could cause an application using the OpenSSL Certificate Revocation List (CRL) checking functionality to incorrectly accept a CRL that has a nextUpdate date in the past. (CVE-2011-3207)
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.
