Descriptions
The SSLv2 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a allows remote attackers to cause a denial of service (s2_lib.c assertion failure and daemon exit) via a crafted CLIENT-MASTER-KEY message.
La implementación SSLv2 en OpenSSL anterior a 0.9.8zf, 1.0.0 anterior a 1.0.0r, 1.0.1 anterior a 1.0.1m, y 1.0.2 anterior a 1.0.2a permite a atacantes remotos causar una denegación de servicio (fallo de aserción s2_lib.c y salida del demonio) a través de un mensaje CLIENT-MASTER-KEY manipulado.
A denial of service flaw was found in the way OpenSSL handled SSLv2 handshake messages. A remote attacker could use this flaw to cause a TLS/SSL server using OpenSSL to exit on a failed assertion if it had both the SSLv2 protocol and EXPORT-grade cipher suites enabled.
