Descriptions

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.

openvpnserv.exe (también conocido como interactive service helper) en OpenVPN en versiones 2.4.x anteriores a la 2.4.6 permite que un atacante local provoque una doble liberación (double free) de memoria enviando una petición mal formada al servicio interactivo. Esto podría provocar una denegación de servicio (DoS) al corromper la memoria o, posiblemente, otro impacto no especificado, incluyendo el escalado de privilegios.
