Synopsis
========

A vulnerability in Ark might allow remote attackers to execute
arbitrary code.

Background
==========

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

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 kde-apps/ark < 16.08.3-r1 >= 16.08.3-r1

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

A vulnerability was discovered in how Ark handles executable files
while browsing a compressed archive. A user could unintentionally
execute a malicious script which has the executable bit set inside of
the archive. This is due to Ark not displaying what files are
executable and running the associated applications for the file type
upon execution.

Impact
======

A remote attacker, by coercing a user to browse a malicious archive
file within Ark and execute certain files, could execute arbitrary code
with the privileges of the user.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Ark users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-apps/ark-16.08.3-r1"

References
==========
