Synopsis
========

Ark was found to allow arbitrary file overwrite, possibly allowing
arbitrary code execution.

Background
==========

Ark is a graphical file compression/decompression utility with support
for multiple formats.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------

Description
===========

Impact
======

A remote attacker could entice a user to open a specially crafted tar
archive using KDE Ark, possibly resulting in execution of arbitrary
code with the privileges of the process or a Denial of Service
condition.

Workaround

Resolution
==========

All KDE Ark users should upgrade to the latest version:

# emerge --sync
