Arch Linux: ASA-201701-18 High Risk: Ark Command Execution

Arch Linux Security Advisory ASA-201701-18
=========================================
Severity: High
Date    : 2017-01-13
CVE-ID  : CVE-2017-5330
Package : ark
Type    : arbitrary command execution
Remote  : No
Link    : https://security.archlinux.org/AVG-130

Summary
======
The package ark before version 16.12.1-1 is vulnerable to arbitrary
command execution.

Resolution
=========
Upgrade to 16.12.1-1.

# pacman -Syu "ark>=16.12.1-1"

The problem has been fixed upstream in version 16.12.1.

Workaround
=========
None.

Description
==========
Opening an url with ark will call KRUN::runURL() which detects the
mime-type of the url and runs the appropriate service for that mimetype
when found. This leads to unintended execution of scripts and
executable files.

Impact
=====
An attacker can execute arbitrary command on the affected host by
tricking a user into opening an executable file from an archive.
