Descriptions

X.Org xdm 1.1.10, 1.1.11, and possibly other versions, when performing authentication using certain implementations of the crypt API function that can return NULL, allows remote attackers to cause a denial of service (NULL pointer dereference and crash) by attempting to log into an account whose password field contains invalid characters, as demonstrated using the crypt function from glibc 2.17 and later with (1) the "!" character in the salt portion of a password field or (2) a password that has been encrypted using DES or MD5 in FIPS-140 mode.

X.Org xdm 1.1.10, 1.1.11 y posiblemente otras versiones, cuando se ejecuta la autenticación utilizando ciertas implementaciones de la función crypt de la API, que puede devolver NULL, permite a atacantes remotos causar denegación de servicio (referencia a puntero a NULL y caída) mediante el intento de acceder a una cuenta cuyo campo de contraseña contiene caracteres inválidos, como se muestra utilizando la función crypt de glibc 2.17 y posteriores con (1) el caracter "!" en la parte del salt de la contraseña (2) una contraseña que ha sido cifrado utilizando DES o MD5 en modo FIPS-140.
