Ubuntu Security Notice USN-4461-1
August 18, 2020

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

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

- Ubuntu 20.04 LTS
- Ubuntu 18.04 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:

Dominik Penner discovered that Ark did not properly sanitize zip archive
files before performing extraction. An attacker could use this to construct
a malicious zip 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 4:19.12.3-0ubuntu1.1

Ubuntu 18.04 LTS:
ark 4:17.12.3-0ubuntu1.1

After a standard system update you need to restart Ark to make all
the necessary changes.
