Red Hat Enterprise Linux 6.5 Patch RHSA-2016:2802-01 for OpenSSL Leak

red hat
Calendar Grey November 17, 2016
Scroller Redhat
Patch released for openssl resolving critical memory leakage concern on Red Hat Enterprise Linux versions.
An update for openssl is now available for Red Hat Enterprise Linux 6.2 Advanced Update Support, Red Hat Enterprise Linux 6.4 Advanced Update Support, Red Hat Enterprise Linux 6.5 ...

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted.

Summary

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library.
Security Fix(es):
* A memory leak flaw was found in the way OpenSSL handled TLS status request extension data during session renegotiation. A remote attacker could cause a TLS server using OpenSSL to consume an excessive amount of memory and, possibly, exit unexpectedly after exhausting all available memory, if it enabled OCSP stapling support. (CVE-2016-6304)
Red Hat would like to thank the OpenSSL project for reporting this issue. Upstream acknowledges Shi Lei (Gear Team of Qihoo 360 Inc.) as the original reporter.
