A malicious server can crash the client + with a null pointer dereference (read) by specifying an anonymous (EC)DH + ciphersuite and sending carefully crafted handshake messages. + + Thanks to Felix Gröbert (Google) for discovering and researching this + issue. + (CVE-2014-3510) + [Emilia Käsper] + + *) By sending carefully crafted DTLS packets an attacker could cause openssl + to leak memory. This can be exploited through a Denial of Service attack. + Thanks to Adam Langley for discovering and researching this issue. + (CVE-2014-3507) + [Adam Langley] + + *) An attacker can force openssl to consume large amounts of memory whilst + processing DTLS handshake messages. This can be exploited through a + Denial of Service attack. + Thanks to Adam Langley for discovering and researching this issue. + (CVE-2014-3506) + [Adam Langley] + + *) An attacker can force an error condition which causes openssl to crash + whilst processing DTLS packets due to memory being freed twice. This + can be exploited through a Denial of Service attack. + Thanks to Adam Langley and Wan-Teh Chang for discovering and researching + this issue. + (CVE-2014-3505) + [Adam Langley] + + *) A flaw in OBJ_obj2txt may cause pretty printing functions such as + X509_name_oneline, X509_name_print_ex et al. to leak some information + from the stack. Applications may be affected if they echo pretty printing + output to the attacker. + + Thanks to Ivan Fratric (Google) for discovering this issue. + (CVE-2014-3508) + [Emilia Käsper, and Steve Henson] + *) Fix ec_GFp_simple_points_make_affine (thus, EC_POINTs_mul etc.) for corner cases. (Certain input points at infinity could lead to bogus results, with non-infinity inputs mapped to infinity too.) |
