Ubuntu Security Notice USN-1181-1
28th July, 2011
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS
An attacker could send crafted URLs to a SoupServer application and obtain unintended access to files.
- libsoup2.4 - HTTP client/server library for GNOME
It was discovered that libsoup did not properly validate its input when
processing SoupServer requests. A remote attacker could exploit this to
access files via directory traversal.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 11.04:
- libsoup2.4-1 2.34.0-0ubuntu1.1
- Ubuntu 10.10:
- libsoup2.4-1 2.31.92-0ubuntu1.1
- Ubuntu 10.04 LTS:
- libsoup2.4-1 2.30.2-0ubuntu0.2
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system update you need to restart any applications that
use libsoup to make all the necessary changes.
