Issue Overview:
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.
The OpenSSL Security Advisory [22 Sep 2016] ("https://www.openssl.org/news/secadv/20160922.txt) refers to additional CVEs. CVE-2016-6305 does not affect OpenSSL 1.0.1. The remaining CVEs listed will be fixed in a later update.
The OpenSSL Security Advisory [26 Sep 2016] (https://www.openssl.org/news/secadv/20160926.txt) refers to two additional CVEs which do not affect OpenSSL 1.0.1.
(Updated 2016-09-26: Included a reference to the 26 Sep 2016 upstream advisory.)
