CVSS: 5.9EPSS: 0%CPEs: 17EXPL: 1CVE-2023-28321 – curl: IDN wildcard match may lead to Improper Cerificate Validation
https://notcve.org/view.php?id=CVE-2023-28321
An improper certificate validation vulnerability exists in curl <v8.1.0 in the way it supports matching of wildcard patterns when listed as "Subject Alternative Name" in TLS server certificates. curl can be built to use its own name matching function for TLS rather than one provided by a TLS library. This private wildcard matching function would match IDN (International Domain Name) hosts incorrectly and could as a result accept patterns that otherwise should mismatch. IDN hostnames are converted to puny code before used for certificate checks. Puny coded names always start with `xn--` and should not be allowed to pattern match, but the wildcard check in curl could still check for `x*`, which would match even though the IDN name most likely contained nothing even resembling an `x`. A flaw was found in the Curl package. • http://seclists.org/fulldisclosure/2023/Jul/47 http://seclists.org/fulldisclosure/2023/Jul/48 http://seclists.org/fulldisclosure/2023/Jul/52 https://hackerone.com/reports/1950627 https://lists.debian.org/debian-lts-announce/2023/10/msg00016.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F4I75RDGX5ULSSCBE5BF3P5I5SFO7ULQ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/Z2LIWHWKOVH24COGGBCVOWDXXIUPKOMK https://security.gentoo • CWE-295: Improper Certificate Validation •

CVSS: 7.5EPSS: 0%CPEs: 5EXPL: 0CVE-2023-32067 – 0-byte UDP payload DoS in c-ares
https://notcve.org/view.php?id=CVE-2023-32067
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. A vulnerability was found in c-ares. • https://github.com/c-ares/c-ares/releases/tag/cares-1_19_1 https://github.com/c-ares/c-ares/security/advisories/GHSA-9g78-jv2r-p7vc https://lists.debian.org/debian-lts-announce/2023/06/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/B5Z5XFNXTNPTCBBVXFDNZQVLLIE6VRBY https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/UBFWILTA33LOSV23P44FGTQQIDRJHIY7 https://security.gentoo.org/glsa/202310-09 https://security.n • CWE-400: Uncontrolled Resource Consumption •
CVSS: 6.4EPSS: 0%CPEs: 5EXPL: 0CVE-2023-31130 – Buffer Underwrite in ares_inet_net_pton()
https://notcve.org/view.php?id=CVE-2023-31130
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. A vulnerability was found in c-ares. • https://github.com/c-ares/c-ares/releases/tag/cares-1_19_1 https://github.com/c-ares/c-ares/security/advisories/GHSA-x6mf-cxr9-8q6v https://lists.debian.org/debian-lts-announce/2023/06/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/B5Z5XFNXTNPTCBBVXFDNZQVLLIE6VRBY https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/UBFWILTA33LOSV23P44FGTQQIDRJHIY7 https://security.gentoo.org/glsa/202310-09 https://security.n • CWE-124: Buffer Underwrite ('Buffer Underflow') CWE-787: Out-of-bounds Write •
