Package        : ark
Version        : 4:16.08.3-2+deb9u1
CVE ID         : CVE-2020-16116 CVE-2020-24654
Debian Bug     : 969437

Fabian Vogt and Dominik Penner discovered that the Ark archive manager did not
sanitize extraction paths, which could result in maliciously crafted archives
with symlinks writing outside the extraction directory.
 
For Debian 9 stretch, these problems have been fixed in version
4:16.08.3-2+deb9u1.

We recommend that you upgrade your ark packages.
