CVE-2021-22883 log

Source
Severity Medium
Remote Yes
Type Denial of service
Description 
Node.js before versions 15.10.0, 14.16.0, 12.21.0 and 10.24.0 is 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.
