USN-1207-1: CUPS vulnerabilities

14 September 2011

An attacker could send crafted print jobs to CUPS and cause it to crash or run programs.



  • cups - Common UNIX Printing System(tm) - server
  • cupsys - Common UNIX Printing System(tm) - server


Tomas Hoger discovered that the CUPS image library incorrectly handled LZW
streams. A remote attacker could use this flaw to cause a denial of service
or possibly execute arbitrary code.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 8.04
Ubuntu 11.04
Ubuntu 10.10
Ubuntu 10.04

In general, a standard system update will make all the necessary changes.
