VCID-3euu-x4gm-aaah
Aliases: CVE-2020-8277 |
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 DNS record with a larger number of responses. This is fixed in 15.2.1, 14.15.1, and 12.19.1. |
Affected by 3 other vulnerabilities. |
|
VCID-5uhr-uasq-aaak
Aliases: CVE-2021-3672 |
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 highest threat from this vulnerability is to confidentiality and integrity as well as system availability. |
Affected by 10 other vulnerabilities. Affected by 3 other vulnerabilities. |
|
VCID-7d9v-uz7u-aaag
Aliases: CVE-2023-32067 GHSA-9g78-jv2r-p7vc |
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. |
Affected by 0 other vulnerabilities. Affected by 3 other vulnerabilities. |
|
VCID-bukj-6xnc-aaar
Aliases: CVE-2022-4904 |
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. |
Affected by 0 other vulnerabilities. Affected by 3 other vulnerabilities. |
|
VCID-csun-gvnt-aaak
Aliases: CVE-2020-14354 |
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. |
Affected by 3 other vulnerabilities. |
|
VCID-dq5b-2fna-aaab
Aliases: CVE-2023-31130 GHSA-x6mf-cxr9-8q6v |
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 configure such an address via ares_set_sortlist(). However, users may externally use ares_inet_net_pton() for other purposes and thus be vulnerable to more severe issues. This issue has been fixed in 1.19.1. |
Affected by 0 other vulnerabilities. Affected by 3 other vulnerabilities. |
|
VCID-jzs1-a8ft-aaab
Aliases: CVE-2020-22217 |
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. |
Affected by 0 other vulnerabilities. Affected by 3 other vulnerabilities. |
|
VCID-kh8m-p7pa-aaap
Aliases: CVE-2016-5180 |
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. |
Affected by 9 other vulnerabilities. Affected by 8 other vulnerabilities. |
|
VCID-xk13-p8qc-aaae
Aliases: CVE-2017-1000381 |
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. |
Affected by 10 other vulnerabilities. |
