Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-7067-1 advisory.

 It was discovered that HAProxy did not properly limit the creation of new HTTP/2 streams. A remote attacker could possibly use this issue to cause HAProxy to consume excessive resources, leading to 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

Update the affected haproxy and / or vim-haproxy packages.
