high Nessus Plugin ID 117934

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3784-1 advisory.

As a security improvement, this update adjusts the private-files abstraction to disallow writing to thumbnailer configuration files. Additionally adjust the private-files, private-files-strict and user- files abstractions to disallow writes on parent directories of sensitive files.

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
