Description
SIPGO is a library for writing SIP services in the GO language. Prior to 1.4.3, WSConnection.Read in sip/transport_ws.go creates a wsutil.Reader without setting MaxFrameSize, allowing NextFrame to accept a client-controlled header.Length before ParseMaxMessageLength is applied. An unauthenticated WS or WSS peer can send a frame header declaring an extremely large payload, causing an oversized allocation or a makeslice length panic before the payload is read and crashing or exhausting memory in the server process. This issue is fixed in version 1.4.3.
