Descripción
gnutls_cipher.c en libgnutls en GnuTLS antes de v2.12.17 y v3.x antes de v3.0.15 no maneja adecuadamente los datos cifrados con un cifrado de bloques, lo que permite provocar una denegación de servicio (corrupción de la pila de memoria y caída de la aplicación) a atacantes remotos a través de un registro hecho a mano, como se demuestra por una estructura GenericBlockCipher especificamente creada para este fin.
