## Description:
This update for tomcat11 fixes the following issues:
Update to Tomcat 11.0.24.
Security issues fixed:
* CVE-2026-59083: incorrect URL decoding in `RewriteValve` may allow security
control bypass (bsc#1271397).
* CVE-2026-59084: `EncryptInterceptor` requirements are not clearly documented
(bsc#1271398).
Other updates and bugfixes:
* Tomcat 11.0.24:
* Catalina
* Fix: Avoid a race condition with concurrent lookups for a singleton JNDI resource. (markt)
* Fix: Improve the performance of range validation for the default servlet. (markt)
* Fix: Avoid NPE in RewriteValve. (markt)
* Fix: 70127: Fix use of Bootstrap through reflection by restoring the public constructor. Use through scripts was not affected. (remm)
* Fix: Restore ability to extend many element classes from AbstractAccessLogValve. (remm)
* Fix: Align DIGEST authentication with RFC 7616 and require clients to provide a valid qop parameter. (markt)
* Fix: Use Files API to create temporary docBase when antiLockingDocBase is enabled. (markt)
* Fix: Improve validation of configuration when DataSourceRealm starts. (remm)
* Fix: JAASRealm should do a logout if login does not fail outright but does not produce a Principal. (remm)
* Fix: Various edge cases for SSI substitutions, quoting and escaping.
* Fix: unintentional conversion of literal + to a space during rule processing in the RewriteValve. (markt)
* Coyote
* Fix: Avoid a potential JVM crash if a suitable version of Tomcat Native is not available when the connector is explicitly configured to use Tomcat Native with OpenSSL for TLS. (markt)
* Jasper
* Fix: 70120: The fix for 69399 (itself a fix for a regression in the fix for 69333) was incomplete and tags that threw exceptions in doStartTag() and doEndTag() were incorrectly re-used. This fix prevents tags from being re-used if such an exception occurs. (markt)
* Add: support for specifying Java 28 (with the value 28) as the compiler source and/or compiler target for JSP compilation. If used with an Eclipse JDT compiler version that does not support these values, a warning will be logged and the default will be used. (markt)
* WebSocket
* Fix: 70126: Fix WebSocket extension permessage-deflate so that it does not drop bytes if a compressed message inflates to more than the available buffer. Fix written by GPT-5.5. Test case written by Hironori Ichimiya. (markt)
* Fix: Optimise WebSocket client processing of server responses during WebSocket HTTP upgrade process. (markt)
* Other
* Update: to the Eclipse JDT compiler 4.40. (markt)
* Update: Byte Buddy to 1.18.9. (markt)
* Update: UnboundID to 7.0.5. (markt)
* Update: JaCoCo to 0.8.15. (markt)
* Update: BND to 7.3.0. (markt)
* Add: Improvements to French translations. (remm)
* Add: Improvements to Japanese translations provided by tak7iji. (markt)
