"Node.js reports :

Updates are now available for v10,x, v12.x and v14.x Node.js release
lines for the following issues. HTTP Request Smuggling due to
CR-to-Hyphen conversion (High) (CVE-2020-8201) Affected Node.js
versions converted carriage returns in HTTP request headers to a
hyphen before parsing. This can lead to HTTP Request Smuggling as it
is a non-standard interpretation of the header.

Impacts :

- All versions of the 14.x and 12.x releases line Denial of Service by
resource exhaustion CWE-400 due to unfinished HTTP/1.1 requests
(Critical) (CVE-2020-8251) Node.js is vulnerable to HTTP denial of
service (DOS) attacks based on delayed requests submission which can
make the server unable to accept new connections. The fix a new
http.Server option called requestTimeout with a default value of 0
which means it is disabled by default. This should be set when Node.js
is used as an edge server, for more details refer to the
documentation.

Impacts :

- All versions of the 14.x release line fs.realpath.native on may
cause buffer overflow (Medium) (CVE-2020-8252) libuv's realpath
implementation incorrectly determined the buffer size which can result
in a buffer overflow if the resolved path is longer than 256 bytes.

Impacts :

- All versions of the 10.x release line

- All versions of the 12.x release line

- All versions of the 14.x release line before 14.9.0");
