Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 23.10 host has packages installed that are affected by a vulnerability as referenced in the USN-6676-1 advisory.

 Vojtch Vobr discovered that c-ares incorrectly handled user input from

 local configuration files. An attacker could possibly use this issue to

 cause a denial of service via application crash.

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.
