Description: 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. 4. 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. 5. Bugs fixed (https://bugzilla.redhat.com/): 1377600 - CVE-2016-6304 openssl: OCSP Status Request extension unbounded memory growth 6.
