Fedora 31 : openvpn (2020-e56f2deb30)

low Nessus Plugin ID 136000

Language:

Synopsis

The remote Fedora host is missing a security update.

Description

Update to latest upstream OpenVPN 2.4.9 release. It contains a security fix for CVE-2020-11810.

This security issue is quite hard to abuse, requiring a fairly precise timing attack combined with guessing a just assigned peer-id reference. If successful, only a single client just initiating a new connection will experience a denial of service situation. This wi why the severity is rated low.

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 openvpn package.
