|---|---|---|---|---|---|---|---|
| CVE-2023-32067 | Hig | 7.5 | < 1.9.1-9.12.1 | 1.9.1-9.12.1 | May 25, 2023 | 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 lengt | |
| CVE-2023-31147 | Med | 5.9 | < 1.9.1-9.12.1 | 1.9.1-9.12.1 | May 25, 2023 | 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 ra | |
| CVE-2023-31130 | Med | 4.1 | < 1.9.1-9.12.1 | 1.9.1-9.12.1 | May 25, 2023 | c-ares is an asynchronous resolver library. ares_inet_net_pton() is vulnerable to a buffer underflow for certain ipv6 addresses, in particular "0::00:00:00/2" was found to cause an issue. C-ares only uses this function internally for configuration purposes which would require an | |
