OpenSSL Issues Fix
The OpenSSL server has been patched to repair a critical security glitch that could be exploited in remote code execution attacks.
OpenSSL is a toolkit that implements Secure Sockets Layer and Transport Layer Security protocols, as well as a full strength, general purpose cryptography library.
The race condition flaw was found in the OpenSSL TLS server extension parsing code, affecting some multithreaded OpenSSL applications. Researchers at Red Hat Security, which relies on OpenSSL for an array of Red Hat Enterprise Linux products, warned in an advisory that under certain conditions, attackers could exploit the vulnerability by triggering a race condition that could cause the OpenSSL application to crash, or enable them to launch of a malicious attack.
The vulnerability, which Red Hat Security researchers ranked as "important" on their Common Vulnerability Scoring System, affects all versions of the OpenSSL supporting TLS extensions, including OpenSSL 0.9.8f through 0.9.8o, 1.0.0 and 1.0.0a.
