Packages

  • ark - archive utility

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.
