Se han descubierto múltiples vulnerabilidades en YaSSL, una implementación de SSL incluida en MySQL, en las versiones YaSSL 1.7.5 y anteriores. Las vulnerabilidades son descritas a continuación: - CVE-2008-0226: Se han descubierto múltiples desbordamientos de búfer. Las vulnerabilidades residen en un error en la comprobación de los límites en la función "ProcessOldClientHello" del fichero "handshake.cpp" y en "input_buffer& operator>>" del fichero "yassl_imp.cpp". Un atacante remoto podría ejecutar código arbitrario mediante un paquete "Hello" SSL versión 2 o versión 3 especialmente diseñado. - CVE-2008-0227: La vulnerabilidad reside en un error en la validación de la entrada en la función "HASHwithTransform::Update" del fichero "hash.cpp". Un atacante remoto podría causar una denegación de servicio mediante un paquete Hello con un valor grande de "size". Existe una prueba de concepto disponible. |
