Samuli Seppänen reports:

In May/June 2017 Guido Vranken threw a fuzzer at OpenVPN 2.4.2. In the process he found several vulnerabilities and reported them to the OpenVPN project. [...] The first releases to have these fixes are OpenVPN 2.4.3 and 2.3.17. This is a list of fixed important vulnerabilities:

Remotely-triggerable ASSERT() on malformed IPv6 packet Pre-authentication remote crash/information disclosure for clients Potential double-free in --x509-alt-username Remote-triggerable memory leaks Post-authentication remote DoS when using the --x509-track option Null-pointer dereference in establish_http_proxy_passthru()
