What's new in OpenSSL 1.0.2:

  • 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. (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]

1 OpenSSL Screenshot:
OpenSSL brings the the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols but also includes a general purpose cryptography library.

The OpenSSL project is managed and maintained by a worldwide community of volunteers that use the Internet to plan, communicate, and develop the OpenSSL toolkit and its related documentation.
