high Nessus Plugin ID 147986

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-4744-1 advisory.

 Pasi Saarinen discovered that OpenLDAP incorrectly handled certain short timestamps. A remote attacker could possibly use this issue to cause OpenLDAP to crash, resulting in a denial of service.

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
