Red Hat Enterprise Linux 5: RHSA-2016-1137-01 Critical OpenSSL Memory Issue

red hat
Calendar Grey May 31, 2016
Scroller Redhat
A critical security vulnerability in OpenSSL for Red Hat Enterprise Linux requires immediate updates to ensure system safety and integrity
An update for openssl is now available for Red Hat Enterprise Linux 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 flaw was found in the way OpenSSL encoded certain ASN.1 data structures. An attacker could use this flaw to create a specially crafted certificate which, when verified or re-encoded by OpenSSL, could cause it to crash, or execute arbitrary code using the permissions of the user running an application compiled against the OpenSSL library. (CVE-2016-2108)
Red Hat would like to thank the OpenSSL project for reporting this issue. Upstream acknowledges Huzaifa Sidhpurwala (Red Hat), Hanno Böck, and David Benjamin (Google) as the original reporters.
