Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS : networkd-dispatcher regression (USN-5395-2)

info Nessus Plugin ID 160519

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-5395-2 advisory.

USN-5395-1 fixed vulnerabilities in networkd-dispatcher. Unfortunately that update was incomplete and could introduce a regression. This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

It was discovered that networkd-dispatcher incorrectly handled internal

scripts. A local attacker could possibly use this issue to cause a race

condition, escalate privileges and execute arbitrary code.

(CVE-2022-29799, CVE-2022-29800)

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 networkd-dispatcher package.
