Descriptions

The FwdState::connectedToPeer method in FwdState.cc in Squid before 3.5.14 and 4.0.x before 4.0.6 does not properly handle SSL handshake errors when built with the --with-openssl option, which allows remote attackers to cause a denial of service (application crash) via a plaintext HTTP message.

El método FwdState::connectedToPeer en FwdState.cc en Squid en versiones anteriores a 3.5.14 y 4.0.x en versiones anteriores a 4.0.6 no maneja correctamente los errores de apretones de manos SSL cuando se construye con la opción --with-openssl, lo que permite a atacantes remotos causar una denegación de servicio (caída de aplicación) a través de un mensaje HTTP en texto plano.
