Debian LTS: DLA-3015-1: ark security update
Summary
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.
