Secunia has released and advisory affecting cups printing system:

  http://secunia.com/advisories/28994/

  Description:
  A vulnerability has been discovered in CUPS, which can be exploited by
  malicious people to cause a DoS (Denial of Service) or to potentially
  compromise a vulnerable system.

  The vulnerability is caused due to an error within the
  "process_browse_data()" function when adding printers and classes. This
  can be exploited to free the same buffer twice by sending specially
  crafted browser packets to the UDP port on which cupsd is listening (by
  default port 631/UDP).

  Successful exploitation may allow execution of arbitrary code.

  The vulnerability is confirmed in version 1.3.5. Prior versions may also
  be affected.

  Solution:
  Update to version 1.3.6.
