Details
Fabian Vogt discovered that Ark incorrectly handled symbolic links in
tar archive files. An attacker could use this to construct a malicious
tar 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
Ubuntu 18.04
Ubuntu 16.04
In general, a standard system update will make all the necessary changes.
