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.


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.


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.
