Ubuntu Security Notice USN-2082-1
15th January, 2014
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.10
- Ubuntu 13.04
- Ubuntu 12.10
CUPS could be made to expose sensitive information.
- cups - Common UNIX Printing System(tm)
Jann Horn discovered that the CUPS lppasswd tool incorrectly read a user
configuration file in certain configurations. A local attacker could use
this to read sensitive information from certain files, bypassing access
The problem can be corrected by updating your system to the following package version:
- Ubuntu 13.10:
- cups-client 1.7.0~rc1-0ubuntu5.2
- Ubuntu 13.04:
- cups-client 1.6.2-1ubuntu8
- Ubuntu 12.10:
- cups-client 1.6.1-0ubuntu11.5
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.
