USN-1276-1: KDE Utilities vulnerability

21 November 2011

kdeutils vulnerability

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

  • Ubuntu 11.10
  • Ubuntu 11.04
  • Ubuntu 10.10
  • Ubuntu 10.04 LTS


Ark could be made to remove files.

Software Description

  • kdeutils - KDE general-purpose utilities


Tim Brown discovered that Ark did not properly perform input validation when previewing archive files. If a user were tricked into opening a crafted archive file, an attacker could remove files via directory traversal.

Update instructions

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

Ubuntu 11.10
ark - 4:4.7.1-0ubuntu3.1
Ubuntu 11.04
ark - 4:4.6.5-0ubuntu1.2
Ubuntu 10.10
ark - 4:4.5.5-0ubuntu2.2
Ubuntu 10.04 LTS
ark - 4:4.4.5-0ubuntu1.2

To update your system, please follow these instructions:

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

NOTE: In order to build KDE Utilities on Ubuntu 10.04 LTS, 10.10 and 11.04, it was necessary to rebuild portions of the KDE point release updates.
