+	<blockquote cite="https://httpd.apache.org/security/vulnerabilities_24.html">
+	  <p>critical: Path Traversal and Remote Code Execution in Apache HTTP
+	  Server 2.4.49 and 2.4.50 (incomplete fix of CVE-2021-41773)
+	  (CVE-2021-42013).</p>
+	  <p>It was found that the fix for CVE-2021-41773 in Apache HTTP
+	  Server 2.4.50 was insufficient. An attacker could use a path
+	  traversal attack to map URLs to files outside the directories
+	  configured by Alias-like directives.</p>
+	  <p>If files outside of these directories are not protected by the
+	  usual default configuration "require all denied", these requests
+	  can succeed. If CGI scripts are also enabled for these aliased
+	  pathes, this could allow for remote code execution.</p>
+	  <p>This issue only affects Apache 2.4.49 and Apache 2.4.50 and not
+	  earlier versions.</p>
