Descriptions

lib/pk-libgcrypt.c in libgnutls in GnuTLS before 2.6.6 does not properly handle invalid DSA signatures, which allows remote attackers to cause a denial of service (application crash) and possibly have unspecified other impact via a malformed DSA key that triggers a (1) free of an uninitialized pointer or (2) double free.

lib/pk-libgcrypt.c en libgnutls en GnuTLS anterior a v2.6.6 no maneja correctamente las firmas DSA, lo cual permite a atacantes remotos provocar una denegación de servicio (cuelgue de aplicación) y posiblemente tiene otro impacto no especificado a través de una clave DSA malformada que desencadena (1) una liberación del puntero no inicializado. (2) una doble liberación.
