Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-5327-1 advisory.

 - In NetKit through 0.17, rcp.c in the rcp client allows remote rsh servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side. This is similar to CVE-2018-20685. (CVE-2019-7282)

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

Solution
