Ubuntu Security Notice USN-1265-1
November 17, 2011

system-config-printer vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.10
- Ubuntu 11.04

Summary:

An attacker could trick system-config-printer into installing altered
packages and repositories.

Software Description:
- system-config-printer: Python modules for printer configuration with CUPS

Details:

Marc Deslauriers discovered that system-config-printer's cupshelpers
scripts used by the Ubuntu automatic printer driver download service
queried the OpenPrinting database using an insecure connection. If a remote
attacker were able to perform a man-in-the-middle attack, this flaw could
be exploited to install altered packages and repositories.

Update instructions:

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

Ubuntu 11.10:
  python-cupshelpers              1.3.6+20110831-0ubuntu9.4

Ubuntu 11.04:
  python-cupshelpers              1.3.1+20110222-0ubuntu16.5

After a standard system update you need to reboot your computer to make
all the necessary changes.
