Use After Free

Affecting node package, versions [,10.23.1) || [11.0.0, 12.20.1) || [13.0.0, 14.15.4) || [15.0.0, 15.5.1)

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.

Remediation

Upgrade node to version 10.23.1, 12.20.1, 14.15.4, 15.5.1 or higher.
