high Nessus Plugin ID 306086

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-8158-1 advisory.

 Fraser Tweedale and Geetika Kapoor discovered that Dogtag PKI could renew a certificate without proper authentication. An attacker could possibly use this to repeatedly renew a compromised certificate and maintain unauthorized access to a system or resource.

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 packages.
