A ReDoS issue was discovered in the Time component through 0.2.1 in Ruby through 3.2.1. The Time parser mishandles invalid URLs that have specific characters. It causes an increase in execution time for parsing strings to Time objects. The fixed versions are 0.1.1 and 0.2.2. A flaw was found in the Time gem and Time library of Ruby. • https://github.com/ruby/time/releases https://lists.debian.org/debian-lts-announce/2023/04/msg00033.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FFZANOQA4RYX7XCB42OO3P24DQKWHEKA https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/G76GZG3RAGYF4P75YY7J7TGYAU7Z5E2T https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WMIOPLBAAM3FEQNAXA2L7BDKOGSVUT5Z https://security.gentoo.org/glsa/202401-27 https://secu • CWE-20: Improper Input Validation CWE-1333: Inefficient Regular Expression Complexity •

A regular expression based DoS vulnerability in Action Dispatch <6.1.7.1 and <7.0.4.1 related to the If-None-Match header. A specially crafted HTTP If-None-Match header can cause the regular expression engine to enter a state of catastrophic backtracking, when on a version of Ruby below 3.2.0. This can cause the process to use large amounts of CPU and memory, leading to a possible DoS vulnerability All users running an affected release should either upgrade or use one of the workarounds immediately. A flaw was found in the rubygem-actionpack. RubyGem's actionpack gem is vulnerable to a denial of service caused by a regular expression denial of service (ReDoS) flaw in Action Dispatch related to the If-None-Match header. • https://discuss.rubyonrails.org/t/cve-2023-22795-possible-redos-based-dos-vulnerability-in-action-dispatch/82118 https://security.netapp.com/advisory/ntap-20240202-0010 https://www.debian.org/security/2023/dsa-5372 https://access.redhat.com/security/cve/CVE-2023-22795 https://bugzilla.redhat.com/show_bug.cgi?id=2164799 • CWE-400: Uncontrolled Resource Consumption CWE-1333: Inefficient Regular Expression Complexity •
