      <description>&lt;p&gt;A regular expression based DoS vulnerability in Action Dispatch &amp;lt;6.1.7.1 and &amp;lt;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.&lt;/p&gt;</description>

      <title>GHSA-8xww-x3g3-6jcv — ReDoS based DoS vulnerability in Action Dispatch</title>
      <link>https://cve.radiocsirt.org/vuln/ghsa-8xww-x3g3-6jcv</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; RubyGems: actionpack&lt;/p&gt;
&lt;p&gt;There is a possible regular expression based DoS vulnerability in Action Dispatch related to the If-None-Match header. This vulnerability has been assigned the CVE identifier CVE-2023-22795.&lt;/p&gt;
&lt;p&gt;Versions Affected: All Not affected: None Fixed Versions: 5.2.8.15 (Rails LTS), 6.1.7.1, 7.0.4.1&lt;/p&gt;
&lt;p&gt;Impact&lt;/p&gt;
&lt;p&gt;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.
Releases&lt;/p&gt;
&lt;p&gt;The FIXED releases are available at the normal locations.
Workarounds&lt;/p&gt;
&lt;p&gt;We recommend that all users upgrade to one of the FIXED versions. In the meantime, users can mitigate this vulnerability by using a load balancer or other device to filter out malicious If-None-Match headers before they reach the application.&lt;/p&gt;
&lt;p&gt;Users on Ruby 3.2.0 or greater are not affected by this vulnerability.
Patches&lt;/p&gt;
&lt;p&gt;To aid users who aren’t able to upgrade immediately we have provided patches for the two supported release series. They are in git-am format and consist of a single changeset.&lt;/p&gt;
&lt;p&gt;6-1-Avoid-regex-backtracking-on-If-None-Match-header.patch - Patch for 6.1 series
    7-0-Avoid-regex-backtracking-on-If-None-Match-header.patch - Patch for 7.0 series&lt;/p&gt;

&#13;
Security Fix(es):&#13;
&#13;
A regular expression based DoS vulnerability in Action Dispatch &amp;amp;lt;6.0.6.1,&amp;amp;lt; 6.1.7.1, and &amp;amp;lt;7.0.4.1. Specially crafted cookies, in combination with a specially crafted X_FORWARDED_HOST header can cause the regular expression engine to enter a state of catastrophic backtracking. 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.(CVE-2023-22792)&#13;
