Descriptions
OpenSSL before 0.9.8y, 1.0.0 before 1.0.0k, and 1.0.1 before 1.0.1d does not properly perform signature verification for OCSP responses, which allows remote OCSP servers to cause a denial of service (NULL pointer dereference and application crash) via an invalid key.
OpenSSL antes de v0.9.8y, v1.0.0 antes de v1.0.0k y v1.0.1 antes de v1.0.1d no realizar correctamente la verificación de firmas para las respuestas OCSP, permite a atacantes remotos provocar una denegación de servicio (desreferencia puntero NULL y caída de la aplicación) a través de una tecla no válida.
OpenSSL before 0.9.8y, 1.0.0 before 1.0.0k, and 1.0.1 before 1.0.1d does not properly perform signature verification for OCSP responses, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an invalid key. The TLS protocol 1.1 and 1.2 and the DTLS protocol 1.0 and 1.2, as used in OpenSSL, OpenJDK, PolarSSL, and other products, do not properly consider timing side-channel attacks on a MAC check requirement during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data for crafted packets, aka the Lucky Thirteen issue. The updated packages have been upgraded to the 1.0.0k version which is not vulnerable to these issues.
