FreeBSD : Node.js -- January 2021 Security Releases (08b553ed-537a-11eb-be6e-0022489ad614)


Node.js reports : use-after-free in TLSWrap (High) (CVE-2020-8265) 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. HTTP Request Smuggling in nodejs (Low) (CVE-2020-8287) 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. OpenSSL - EDIPARTYNAME NULL pointer de-reference (CVE-2020-1971) iThis is a vulnerability in OpenSSL which may be exploited through Node.js.
