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 a package installed that is affected by a vulnerability as referenced in the USN-6685-1 advisory.

 It was discovered that mqtt-client incorrectly handled memory while parsing malformed MQTT frames. An attacker could possibly use this issue to cause a crash, resulting in a denial of service, or possibly execute arbitrary code.

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.
