Unspecified vulnerability in yaSSL before 1.0.6 has unknown impact and attack vectors, related to "certificate chain processing."
Multiple buffer overflows in yaSSL 1.7.5 and earlier, as used in MySQL and possibly other products, allow remote attackers to execute arbitrary code via (1) the ProcessOldClientHello function in handshake.cpp or (2) "inputbuffer& operator>>" in yasslimp.cpp.
