libsoup2.4 vulnerability
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS

Summary:

An attacker could send crafted URLs to a SoupServer application and obtain
unintended access to files.

Software Description:
- libsoup2.4: HTTP client/server library for GNOME

Details:

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.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

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

After a standard system update you need to restart any applications that
use libsoup to make all the necessary changes.
