Details

Aaron Sigel discovered that the CUPS web interface incorrectly protected
against cross-site scripting (XSS) and cross-site request forgery (CSRF)
attacks. If an authenticated user were tricked into visiting a malicious
website while logged into CUPS, a remote attacker could modify the CUPS
configuration and possibly steal confidential data.

Update instructions

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

Ubuntu 9.10

• cups - 1.4.1-5ubuntu2.1

Ubuntu 9.04

• cups - 1.3.9-17ubuntu3.4

Ubuntu 8.10

• cups - 1.3.9-2ubuntu9.3

Ubuntu 8.04

• cupsys - 1.3.7-1ubuntu3.6

Ubuntu 6.06

• cupsys - 1.2.2-0ubuntu0.6.06.15

In general, a standard system upgrade is sufficient to effect the
necessary changes.
