CVE-2020-8265 Open this link in a new tabHow to fix?
Upgrade node to version 10.23.1, 12.20.1, 14.15.4, 15.5.1 or higher.
Overview
node is a JavaScript runtime built on Chrome's V8 JavaScript engine.
Affected versions of this package are vulnerable to Use After Free. When writing to a TLS enabled socket, node::StreamBase::Write calls node::TLSWrap::DoWrite with a freshly allocated WriteWrap object as first argument. 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.
