An attacker using a carefully crafted + handshake can force the use of weak keying material in OpenSSL + SSL/TLS clients and servers. + + Thanks to KIKUCHI Masashi (Lepidum Co. Ltd.) for discovering and + researching this issue. (CVE-2014-0224) + [KIKUCHI Masashi, Steve Henson] + + *) Fix DTLS recursion flaw. By sending an invalid DTLS handshake to an + OpenSSL DTLS client the code can be made to recurse eventually crashing + in a DoS attack. + + Thanks to Imre Rad (Search-Lab Ltd.) for discovering this issue. + (CVE-2014-0221) + [Imre Rad, Steve Henson] + + *) Fix DTLS invalid fragment vulnerability. A buffer overrun attack can + be triggered by sending invalid DTLS fragments to an OpenSSL DTLS + client or server. This is potentially exploitable to run arbitrary + code on a vulnerable client or server. + + Thanks to Jüri Aedla for reporting this issue. (CVE-2014-0195) + [Jüri Aedla, Steve Henson] + + *) Fix bug in TLS code where clients enable anonymous ECDH ciphersuites + are subject to a denial of service attack. + + Thanks to Felix Gröbert and Ivan Fratric at Google for discovering + this issue. (CVE-2014-3470) + [Felix Gröbert, Ivan Fratric, Steve Henson] + + *) Fix for the attack described in the paper "Recovering OpenSSL + ECDSA Nonces Using the FLUSH+RELOAD Cache Side-channel Attack" + by Yuval Yarom and Naomi Benger. Details can be obtained from: + http://eprint.iacr.org/2014/140 + + Thanks to Yuval Yarom and Naomi Benger for discovering this + flaw and to Yuval Yarom for supplying a fix (CVE-2014-0076) + [Yuval Yarom and Naomi Benger] + + Thanks to mancha for backporting the fix to the 0.9.8 branch. + + *) Fix handling of warning-level alerts in SSL23 client mode so they + don't cause client-side termination (eg. on SNI unrecognized_name + warnings). Add client and server support for six additional alerts + per RFC 6066 and RFC 4279. + [mancha] + + *) Add option SSL_OP_SAFARI_ECDHE_ECDSA_BUG (part of SSL_OP_ALL) which + avoids preferring ECDHE-ECDSA ciphers when the client appears to be + Safari on OS X. Safari on OS X 10.8..10.8.3 advertises support for + several ECDHE-ECDSA ciphers, but fails to negotiate them. The bug + is fixed in OS X 10.8.4, but Apple have ruled out both hot fixing + 10.8..10.8.3 and forcing users to upgrade to 10.8.4 or newer. + [Rob Stradling, Adam Langley] + Changes between 0.9.8x and 0.9.8y [5 Feb 2013] *) Make the decoding of SSLv3, TLS and DTLS CBC records constant time. |
