NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs:16/nodejs-devel package and not the nodejs:16/nodejs-devel package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

c-ares is an asynchronous resolver library. When /dev/urandom or RtlGenRandom() are unavailable, c-ares uses rand() to generate random numbers used for DNS query ids. This is not a CSPRNG, and it is also not seeded by srand() so will generate predictable output. Input from the random number generator is fed into a non-compilant RC4 implementation and may not be as strong as the original RC4 implementation. No attempt is made to look for modern OS-provided CSPRNGs like arc4random() that is widely available. This issue has been fixed in version 1.19.1.
