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
-------------------------------------------------------------------
1 kde-apps/ark < 20.04.3-r1 >= 20.04.3-r1

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

A maliciously crafted archive with "../" in the file path(s) could
install files anywhere in the user's home directory upon extraction.

Impact
======

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

Workaround
==========

Avoid opening untrusted archives.

Resolution
==========

All Ark users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-apps/ark-20.04.3-r1"
