VuXML IDDescription
2f3cd69e-7dee-11eb-b92e-0022489ad614Node.js -- February 2021 Security Releases

Node.js reports:

HTTP2 'unknownProtocol' cause Denial of Service by resource exhaustion (Critical) (CVE-2021-22883)

Affected Node.js versions are vulnerable to denial of service attacks when too many connection attempts with an 'unknownProtocol' are established. This leads to a leak of file descriptors. If a file descriptor limit is configured on the system, then the server is unable to accept new connections and prevent the process also from opening, e.g. a file. If no file descriptor limit is configured, then this lead to an excessive memory usage and cause the system to run out of memory.

DNS rebinding in --inspect (CVE-2021-22884)

Affected Node.js versions are vulnerable to a DNS rebinding attack when the whitelist includes "localhost6". When "localhost6" is not present in /etc/hosts, it is just an ordinary domain that is resolved via DNS, i.e., over network. If the attacker controls the victim's DNS server or can spoof its responses, the DNS rebinding protection can be bypassed by using the "localhost6" domain. As long as the attacker uses the "localhost6" domain, they can still apply the attack described in CVE-2018-7160.

OpenSSL - Integer overflow in CipherUpdate (CVE-2021-23840)

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.
