Severity:	normal
Title:	Ark: Arbitrary code execution
Date:	08/08/2020
Bugs:	#734622
ID:	202008-03

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	Architecture(s)
kde-apps/ark	< 20.04.3-r1	>= 20.04.3-r1	All supported architectures

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"
