A possible use-after-free and double-free in c-ares lib version 1.16.0 if ares_destroy() is called prior to ares_getaddrinfo() completing. This flaw possibly allows an attacker to crash the service that uses c-ares lib. The highest threat from this vulnerability is to this service availability.
Mitigation
If calling wait_ares(channel) before ares_destroy() in the service that uses c-ares, then this should prevent this bug.
