Package        : ark
CVE ID         : CVE-2020-16116

Dominik Penner discovered that the Ark archive manager did not sanitise
extraction paths, which could result in maliciously crafted archives
writing outside the extraction directory.

For the stable distribution (buster), this problem has been fixed in
version 4:18.08.3-1+deb10u1.

We recommend that you upgrade your ark packages.
