GLSA-201701-69 : Ark: Unintended execution of scripts and executable files

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-201701-69
(Ark: Unintended execution of scripts and executable files)

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.

All Ark users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=kde-apps/ark-16.08.3-r1'

Risk factor :

Medium / CVSS Base Score : 6.8
