2021-01-04, Version 15.5.1 (Current), @BethGriggs

This is a security release.

Notable changes

Vulnerabilities fixed:

• CVE-2020-8265: use-after-free in TLSWrap (High)

  • Affected Node.js versions are vulnerable to a use-after-free bug in
    its TLS implementation. 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 leading to a Denial of Service or potentially other
    exploits.

• CVE-2020-8287: HTTP Request Smuggling in nodejs (Low)

  • Affected versions of Node.js allow two copies of a header field in
    a http request. For example, two Transfer-Encoding header fields. In
    this case Node.js identifies the first header field and ignores the
    second. This can lead to HTTP Request Smuggling
    (https://cwe.mitre.org/data/definitions/444.html).
