+ applied.</p>
+
+ <p>This was fixed with commit

+
+ <p>The AJP secret was compared in non-constant time allowing an attacker on
+ the local network to mount a timing attack to determine the AJP
+ secret.</p>
+
+ <p>This was fixed with commit

+
+ <p>The LockOut Realm treated user names as case sensitive meaning that, for
+ Realms where the user name was case insensitive, the LockOut Realm was
+ not as effective at blocking brute force attacks against a user's
+ password.</p>
+
+ <p>This was fixed with commit

+
+ <p>When DIGEST authentication was configured, any user not known to the

+ "null".</p>
+
+ <p>This was fixed with commit
+ <a

+
+ <p>If a WebSocket request was redirected after authentication, Tomcat's

+
+ <p>This was fixed with commit
