Ubuntu Security Notice USN-841-1
5th October, 2009
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 9.04
- Ubuntu 8.10
- Ubuntu 8.04 LTS
Arand Nash discovered that applications linked to GLib (e.g. Nautilus)
did not correctly copy symlinks. If a user copied symlinks with GLib,
the symlink target files would become world-writable, allowing local
attackers to gain access to potentially sensitive information.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 9.04:
- libglib2.0-0 2.20.1-0ubuntu2.1
- Ubuntu 8.10:
- libglib2.0-0 2.18.2-0ubuntu2.2
- Ubuntu 8.04 LTS:
- libglib2.0-0 2.16.6-0ubuntu1.2
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system upgrade you need to restart your session to effect
the necessary changes.
