How to fix?

There is no fixed version for RHEL:8 c-ares-devel.

NVD Description

Note: Versions mentioned in the description apply only to the upstream c-ares-devel package and not the c-ares-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 cross-compiling c-ares and using the autotools build system, CARES_RANDOM_FILE will not be set, as seen when cross compiling aarch64 android. This will downgrade to using rand() as a fallback which could allow an attacker to take advantage of the lack of entropy by not using a CSPRNG. This issue was patched in version 1.19.1.
