Brocade Security Advisory
An authenticated client can cause the server's the packet-id counter to roll over, which would lead the server process to hit an ASSERT() and stop running. To make the server hit the ASSERT(), the client must first cause the server to send it 2EXP32 packets (at least 196GB). OpenVPN versions 2.4.2 and 2.3.15 (and later) include these fixes.
