CVE-2023-22467 – luxon.js inefficient regular expression complexity vulnerability

https://notcve.org/view.php?id=CVE-2023-22467

Luxon is a library for working with dates and times in JavaScript. On the 1.x branch prior to 1.38.1, the 2.x branch prior to 2.5.2, and the 3.x branch on 3.2.1, Luxon's `DateTime.fromRFC2822() has quadratic (N^2) complexity on some specific inputs. This causes a noticeable slowdown for inputs with lengths above 10k characters. Users providing untrusted data to this method are therefore vulnerable to (Re)DoS attacks. This issue also appears in Moment as CVE-2022-31129. • https://github.com/moment/luxon/commit/5ab3bf64a10da929a437629cdb2f059bb83212bf https://github.com/moment/luxon/security/advisories/GHSA-3xq5-wjfh-ppjc https://github.com/moment/moment/pull/6015#issuecomment-1152961973 https://github.com/moment/moment/security/advisories/GHSA-wc69-rhjr-hc9g https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/44I3WAJKYXDLOVYRGMHAUXMIV4SPFXDZ https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/4LIVOASKBQH7FEUI5RWM3SOHR6VK7ZZR https • CWE-1333: Inefficient Regular Expression Complexity •
