18 April 2011

kdenetwork vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 10.10
  • Ubuntu 10.04 LTS
  • Ubuntu 9.10

Summary

An attacker could overwrite files owned by the user if KGet opened a crafted metalink file.

Software Description

  • kdenetwork - networking applications for KDE 4

Details

It was discovered that KGet did not properly perform input validation when processing metalink files. If a user were tricked into opening a crafted metalink file, a remote attacker could overwrite files via directory traversal, which could eventually lead to arbitrary code execution.

Update instructions

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

Ubuntu 10.10
kget - 4:4.5.1-0ubuntu2.2
Ubuntu 10.04 LTS
kget - 4:4.4.5-0ubuntu1.1
Ubuntu 9.10
kget - 4:4.3.2-0ubuntu4.5

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

After a standard system update you need to restart KGet to make all the necessary changes.
