Ubuntu Security Notice USN-1276-1
November 21, 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

Summary:

Ark could be made to remove files.

Software Description:
- kdeutils: KDE general-purpose utilities

Details:

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

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.
