Vulnerability of ares_inet_net_pton() function of C-ares asynchronous DNS query library is related to violation of the initial buffer boundary.
the initial buffer boundary. Exploitation of the vulnerability could allow an attacker to gain access to
confidential data, violate its integrity, and cause a denial of service

Vulnerability in autotools CARES_RANDOM_FILE component of C-ares asynchronous DNS queries library is related to
The use of rand() as a fallback, which could allow an attacker to take advantage of the lack of entropy without having to use rand().
exploit the lack of entropy without using CSPRNG. Exploitation of the vulnerability could allow
An attacker acting remotely to disclose protected information
