| CVE-2024-25629 | 3 C-ares, Fedoraproject, Redhat | 5 C-ares, Fedora, Enterprise Linux and 2 more | 2025-02-13 | 4.4 Medium |
| c-ares is a C library for asynchronous DNS requests. `ares__read_line()` is used to parse local configuration files such as `/etc/resolv.conf`, `/etc/nsswitch.conf`, the `HOSTALIASES` file, and if using a c-ares version prior to 1.27.0, the `/etc/hosts` file. If any of these configuration files has an embedded `NULL` character as the first character in a new line, it can lead to attempting to read memory prior to the start of the given buffer which may result in a crash. This issue is fixed in c-ares 1.27.0. No known workarounds exist. | ||||
| CVE-2023-32067 | 5 C-ares, C-ares Project, Debian and 2 more | 10 C-ares, C-ares, Debian Linux and 7 more | 2025-02-13 | 7.5 High |
| 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 shutdown of the connection. This issue has been patched in version 1.19.1. | ||||
| CVE-2020-22217 | 3 C-ares, Debian, Redhat | 4 C-ares, Debian Linux, Enterprise Linux and 1 more | 2024-11-21 | 5.9 Medium |
| Buffer overflow vulnerability in c-ares before 1_16_1 thru 1_17_0 via function ares_parse_soa_reply in ares_parse_soa_reply.c. | ||||
| CVE-2020-14354 | 2 C-ares, Fedoraproject | 2 C-ares, Fedora | 2024-11-21 | 3.3 Low |
| A possible use-after-free and double-free in c-ares lib version 1.16.0 if ares_destroy() is called prior to ares_getaddrinfo() completing. This flaw possibly allows an attacker to crash the service that uses c-ares lib. The highest threat from this vulnerability is to this service availability. | ||||
| CVE-2017-1000381 | 4 C-ares, C-ares Project, Nodejs and 1 more | 4 C-ares, C-ares, Node.js and 1 more | 2024-11-21 | 7.5 High |
| 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 particular way. | ||||
| CVE-2016-5180 | 6 C-ares, C-ares Project, Canonical and 3 more | 6 C-ares, C-ares, Ubuntu Linux and 3 more | 2024-11-21 | 9.8 Critical |
| 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 an escaped trailing dot. | ||||
