New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Fedora host is missing a security update.

Description

This update includes the latest upstream release of mod_http2, version 1.10.16. This includes a security fix (CVE-2018-1302) :

When an HTTP/2 stream was destroyed after being handled, mod_http2 could have written a NULL pointer potentially to an already freed memory.

The memory pools maintained by the server make this vulnerabilty hard to trigger in usual configurations, the reporter and the team could not reproduce it outside debug builds, so it is classified as low risk.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected mod_http2 package.
