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
