Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-6711-1 advisory.

 Vincent Berg discovered that CRM shell incorrectly handled certain commands. An local attacker could possibly use this issue to execute arbitrary code via shell code injection to the crm history commandline.

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.
