Description Dhananjay Arunesh 2020-07-17 08:33:07 UTC 
OpenVPN Access Server older than version 2.8.4 generates new user authentication tokens instead of reusing exiting tokens on reconnect making it possible to circumvent the initial token expiry timestamp.

Comment 1 David Sommerseth 2020-07-17 09:24:37 UTC 
Again, this is OpenVPN *ACCESS SERVER* ... this is NOT the open source OpenVPN code base, even though Access Server builds on the open source code.  And Access Server is NOT packaged in ANY Fedora or RHEL repositories which is under Red Hat or Fedora's control.

For the future, PLEASE GET IN TOUCH with the community or OpenVPN INC (at least reach out to security) to verify if this affects the open source version of OpenVPN or not before filing such nonsense tickets like this.


kind regards,
