How to fix?

Upgrade node to version 16.20.1, 18.16.1, 20.3.1 or higher.

Overview

node is a JavaScript runtime built on Chrome's V8 JavaScript engine.

Affected versions of this package are vulnerable to Buffer Underwrite (Buffer Underflow) in the ares_inet_net_pton() function. C-ares only uses this function internally for configuration purposes which would require an administrator to configure such an address via ares_set_sortlist(). However, users may externally use ares_inet_net_pton() for other purposes and thus be vulnerable to more severe issues.
