"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) This is a vulnerability in
OpenSSL which may be exploited through Node.js. You can read more
about it in https://www.openssl.org/news/secadv/20210216.txt");
