Ubuntu Security Notice USN-4482-1
September 01, 2020

ark vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

Ark could be made to write files as your login if it opened a specially
crafted file.

Software Description:
- ark: archive utility

Details:

Fabian Vogt discovered that Ark incorrectly handled symbolic links in
tar archive files. An attacker could use this to construct a malicious
tar archive that, when opened, would create files outside the extraction
directory.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 20.04 LTS:
ark 4:19.12.3-0ubuntu1.2

Ubuntu 18.04 LTS:
ark 4:17.12.3-0ubuntu1.2

Ubuntu 16.04 LTS:
ark 4:15.12.3-0ubuntu1.2

In general, a standard system update will make all the necessary changes.
