Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS / 22.04 LTS / 23.04 / 23.10 : Avahi vulnerabilities (USN-6487-1)

medium Nessus Plugin ID 186016

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS / 22.04 LTS / 23.04 / 23.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6487-1 advisory.

 Evgeny Vereshchagin discovered that Avahi contained several reachable

 assertions, which could lead to intentional assertion failures when

 specially crafted user input was given. An attacker could possibly use this issue to cause a denial of service. (CVE-2023-38469, CVE-2023-38470, CVE-2023-38471, CVE-2023-38472, CVE-2023-38473)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Solution

Update the affected packages.
