Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM : oddjob vulnerability (USN-5169-1)

medium Nessus Plugin ID 183152

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-5169-1 advisory.

 Matthias Gerstner discovered that there was a race condition in the mkhomedir tool shipped with the oddjob package. An authenticated attacker could use this to setup a symlink attack and change permissions on files on the host filesystem.

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 oddjob and / or oddjob-mkhomedir packages.
