Name : openvpn
Product : Fedora 31
Version : 2.4.9
Release : 1.fc31
URL : https://community.openvpn.net/
Summary : A full-featured SSL VPN solution
Description :
OpenVPN is a robust and highly flexible tunneling application that uses all
of the encryption, authentication, and certification features of the
OpenSSL library to securely tunnel IP networks over a single UDP or TCP
port. It can use the Marcus Franz Xaver Johannes Oberhumers LZO library
for compression.

Update Information:

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.
