Ubuntu Security Notice USN-2172-1
24th April, 2014
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.10
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS
CUPS could be made to expose sensitive information over the network.
- cups - Common UNIX Printing System(tm)
Alex Korobkin discovered that the CUPS web interface incorrectly protected
against cross-site scripting (XSS) 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
The problem can be corrected by updating your system to the following package version:
- Ubuntu 13.10:
- cups 1.7.0~rc1-0ubuntu5.3
- Ubuntu 12.10:
- cups 1.6.1-0ubuntu11.6
- Ubuntu 12.04 LTS:
- cups 1.5.3-0ubuntu8.2
- Ubuntu 10.04 LTS:
- cups 1.4.3-1ubuntu1.11
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
