Descriptions

gnutls_cipher.c in libgnutls in GnuTLS before 2.12.17 and 3.x before 3.0.15 does not properly handle data encrypted with a block cipher, which allows remote attackers to cause a denial of service (heap memory corruption and application crash) via a crafted record, as demonstrated by a crafted GenericBlockCipher structure.

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.

New gnutls packages are available for Slackware 12.1, 12.2, 13.0, 13.1, and 13.37 to fix security issues. Related CVE Numbers: CVE-2011-4128,CVE-2012-1569,CVE-2012-1573,CVE-2013-1619,CVE-2013-2116.
