Package : ark
CVE ID : CVE-2020-24654
Debian Bug : 969437

Fabian Vogt reported that the Ark archive manager did not sanitise
extraction paths, which could result in maliciously crafted archives
with symlinks writing outside the extraction directory.

For the stable distribution (buster), this problem has been fixed in
version 4:18.08.3-1+deb10u2.

We recommend that you upgrade your ark packages.
