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 shuthttps://patchthecve.com/cve/CVE-2023-31147.htmlhttps://patchthecve.com/cve/CVE-2023-31147.htmlWed, 17 Jun 2026 05:56:22 +0000MEDIUM 5.9: 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 generatohttps://patchthecve.com/cve/CVE-2023-31130.htmlhttps://patchthecve.com/cve/CVE-2023-31130.htmlWed, 17 Jun 2026 05:56:20 +0000MEDIUM 4.1: 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 administrator to cohttps://patchthecve.com/cve/CVE-2023-31124.htmlhttps://patchthecve.com/cve/CVE-2023-31124.htmlWed, 17 Jun 2026 05:56:19 +0000LOW 3.7: 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 lachttps://patchthecve.com/cve/CVE-2022-4904.htmlhttps://patchthecve.com/cve/CVE-2022-4904.htmlWed, 17 Jun 2026 05:22:15 +0000HIGH 8.6: A flaw was found in the c-ares package. The ares_set_sortlist is missing checks about the validity of the input string, which allows a possible arbitrary length stack overflow. This issue may cause a denial of service or a limited impact on confidentiality and integrity.
