openvpnserv.exe (aka the interactive service helper) in OpenVPN 2.4.x
before 2.4.6 allows a local attacker to cause a double-free of memory by
sending a malformed request to the interactive service. This could cause a
denial-of-service through memory corruption or possibly have unspecified
other impact including privilege escalation.
