+ Changes between 1.0.1i and 1.0.1j [15 Oct 2014]
+ *) SRTP Memory Leak.
+ A flaw in the DTLS SRTP extension parsing code allows an attacker, who
+ sends a carefully crafted handshake message, to cause OpenSSL to fail
+ to free up to 64k of memory causing a memory leak. This could be
+ exploited in a Denial Of Service attack. This issue affects OpenSSL
+ 1.0.1 server implementations for both SSL/TLS and DTLS regardless of
+ whether SRTP is used or configured. Implementations of OpenSSL that
+ have been compiled with OPENSSL_NO_SRTP defined are not affected.
+ The fix was developed by the OpenSSL team.
+ [OpenSSL team]
+ *) Session Ticket Memory Leak.
+ When an OpenSSL SSL/TLS/DTLS server receives a session ticket the
+ integrity of that ticket is first verified. In the event of a session
+ ticket integrity check failing, OpenSSL will fail to free memory
+ causing a memory leak. By sending a large number of invalid session
+ tickets an attacker could exploit this issue in a Denial Of Service
+ [Steve Henson]
+ *) Build option no-ssl3 is incomplete.
+ When OpenSSL is configured with "no-ssl3" as a build option, servers
+ could accept and complete a SSL 3.0 handshake, and clients could be
+ configured to send them.
+ [Akamai and the OpenSSL team]
+ *) Add support for TLS_FALLBACK_SCSV.
+ Client applications doing fallback retries should call
+ SSL_set_mode(s, SSL_MODE_SEND_FALLBACK_SCSV).
+ [Adam Langley, Bodo Moeller]
+ *) Add additional DigestInfo checks.
+ Reencode DigestInto in DER and check against the original when
+ verifying RSA signature: this will reject any improperly encoded
+ DigestInfo structures.
+ Note: this is a precautionary measure and no attacks are currently known.
+ [Steve Henson]
