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. + (CVE-2014-3513) + [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 + attack. + (CVE-2014-3567) + [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. + (CVE-2014-3568) + [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).
