Node.js is vulnerable to use after free bug. The vulnerability is possible because when writing to a TLS enabled socket, node::StreamBase::Write calls node::TLSWrap::DoWrite with a freshly allocated WriteWrap object as first argument however if the DoWrite method does not return an error, this object is passed back to the caller as part of a StreamWriteResult structure. This may be exploited to corrupt memory leading to a Denial of Service or potentially other exploits.
