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

low Nessus Plugin ID 140180

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected ark package.
