Re: [Openvpn-users] Does OpenVPN use the TLS heartbeat extension? (OpenSSL Security Advisory CVE-2014-0160)

Thanks for the information. I’ll appreciate any further insight on the following: - 1. Should we uninstall and then re-install the 2.3.3 on all Windows clients? Or should we install 2.3.3 without uninstalling previous version? 2. Our server is running on Windows as well. So we will need to install

Just wondering... This bleeding isn't only about openvpn, but all that uses an unpatch openssl-lib. On the heartbleed-bug-live-blog, they advice to regenerate private-key, and request/replace ssl-certificate. Just in case. That is all very well for people using self-signed certs and file based-k

Very true. I mean, a malicious server could compromise clients, but I was thinking more along the lines of malicious clients compromising servers, which would require the server to be un-patched. If you run a server, definitely patch. If you're a client, patch anyway, for reasons beyond openvpn.
