Name : openvpn
Product : Fedora 38
Version : 2.6.8
Release : 1.fc38
URL : https://community.openvpn.net/
Summary : A full-featured TLS VPN solution (beta release)
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:

This is an extended update of the OpenVPN 2.6.7 release which contains security
fixes for CVE-2023-46849 and CVE-2023-46850. That release had a regression
causing the `openvpn` daemon to segfault frequently; which is why the 2.6.7
release was pulled. This 2.6.8 release contains a fix for the regression issue
as well.
