Description: xdm was updated on crypt() NULL pointer crashes: * Starting with glibc 2.17 (eglibc 2.17), crypt() fails with EINVAL (w/ NULL return) if the salt violates specifications. Additionally, on FIPS-140 enabled Linux systems, DES/MD5-encrypted passwords passed to crypt() fail with EPERM (w/ NULL return). If using glibc's crypt(), check return value to avoid a possible NULL pointer dereference.
