Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS : Ark vulnerability (USN-4482-1)

low Nessus Plugin ID 140180

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-4482-1 advisory.

 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.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected ark package.
