References:         #824884 
Cross-References:   CVE-2013-2179
Affected Products:
                    openSUSE 12.3
______________________________________________________________________________

   An update that fixes one vulnerability is now available.

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. (bnc#824884) (CVE-2013-2179)
