CVE-2023-32067

c-ares is an asynchronous resolver library. c-ares is vulnerable to denial of service. If a target resolver sends a query, the attacker forges a malformed UDP packet with a length of 0 and returns them to the target resolver. The target resolver erroneously interprets the 0 length as a graceful...

Design/Logic Flaw

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 i...

CVE-2023-31124

c-ares is an asynchronous resolver library. When cross-compiling c-ares and using the autotools build system, CARESRANDOMFILE 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 ...

CVE-2023-31130

CVE-2023-31130 affects the c-ares asynchronous DNS library. The vulnerability is a buffer underflow/underwrite in ares_inet_net_pton() for IPv6 addresses such as 0::00:00:00/2. Affected versions are prior to the fix, with the issue addressed in c-ares 1.19.1. Multiple advisories reference upgrade...

CVE-2023-31124

CVE-2023-31124 concerns c-ares where cross-compiling with autotools can leave CARES_RANDOM_FILE unset, causing a fallback to rand() for DNS query ID entropy rather than a CSPRNG. The result is reduced randomness and potential predictability of DNS IDs, raising security risk under entropy-limited ...
