Ubuntu Security Notice USN-396-1
14th December, 2006
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 6.10
- Ubuntu 6.06 LTS
A format string vulnerability was discovered in the gdmchooser component
of the GNOME Display Manager. By typing a specially crafted host name,
local users could gain gdm user privileges, which could lead to further
account information exposure.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 6.10:
- gdm 2.16.1-0ubuntu4.1
- Ubuntu 6.06 LTS:
- gdm 2.14.10-0ubuntu1.1
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system upgrade you need to reboot your computer to
effect the necessary changes.
