|---|---|---|---|---|---|
| CVE-2023-32067 | Alta (7.5) | 1.6% | — | 25 may 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… |
| CVE-2023-31147 | Media (6.5) | 0.90% | — | 25 may 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… |
| CVE-2023-31130 | Media (6.4) | 0.38% | — | 25 may 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… |
| CVE-2023-31124 | Baja (3.7) | 0.93% | — | 25 may 2023 | 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… |
| CVE-2022-4904 | Alta (8.6) | 1.2% | — | 6 mar 2023 | 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… |
| CVE-2021-3672 | Media (5.6) | 2.8% | — | 23 nov 2021 | A flaw was found in c-ares library, where a missing input validation check of host names returned by DNS (Domain Name Servers) can lead to output of wrong hostnames which might potentially lead to Domain Hijacking. The… |
| CVE-2020-8277 | Alta (7.5) | 54% | — | 19 nov 2020 | A Node.js application that allows an attacker to trigger a DNS request for a host of their choice could trigger a Denial of Service in versions < 15.2.1, < 14.15.1, and < 12.19.1 by getting the application to resolve a… |
| CVE-2017-1000381 | Alta (7.5) | 3.3% | — | 7 jul 2017 | The c-ares function `ares_parse_naptr_reply()`, which is used for parsing NAPTR responses, could be triggered to read memory outside of the given input buffer if the passed in DNS response packet was crafted in a… |
| CVE-2016-5180 | Crítica (9.8) | 8.6% | — | 3 oct 2016 | Heap-based buffer overflow in the ares_create_query function in c-ares 1.x before 1.12.0 allows remote attackers to cause a denial of service (out-of-bounds write) or possibly execute arbitrary code via a hostname with… |
