   An update that fixes one vulnerability is now available.

Description:

   Bash was fixed to avoid a possible buffer overflow when
   expanding the /dev/fd prefix with e.g. the test builtin
   (bnc#770795) (CVE-2012-3410)

   Due to _FORTIFY_SOURCE=2 enablement, the exploit will only
   abort the shell.
