Ark: Arbitrary code execution — GLSA 202010-06

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

Affected packages

kde-apps/ark on all architectures
Affected versions < 20.04.3-r2
Unaffected versions >= 20.04.3-r2

Background

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

Description

It was discovered that Ark incorrectly handled symbolic links in tar archive files.

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

There is no known workaround at this time.

Resolution

All KDE Ark users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=kde-apps/ark-20.04.3-r2"
