## Description:

This update for tomcat10 fixes the following issues:

  * CVE-2024-24549: Fixed denial of service during header validation for HTTP/2
    stream (bsc#1221386)
  * CVE-2024-23672: Fixed denial of service due to malicious WebSocket client
    keeping connection open (bsc#1221385)

Other fixes: \- Update to Tomcat 10.1.20 * Catalina \+ Fix: Minor performance
improvement for building filter chains. Based on ideas from #702 by Luke Miao.
(remm) \+ Fix: Align error handling for Writer and OutputStream. Ensure use of
either once the response has been recycled triggers a NullPointerException
provided that discardFacades is configured with the default value of true.
(markt) \+ Fix: 68692: The standard thread pool implementations that are
configured using the Executor element now implement ExecutorService for better
support NIO2. (remm) \+ Fix: 68495: When restoring a saved POST request after a
successful FORM authentication, ensure that neither the URI, the query string
nor the protocol are corrupted when restoring the request body. (markt) \+ Fix:
After forwarding a request, attempt to unwrap the response in order to suspend
it, instead of simply closing it if it was wrapped. Add a new
suspendWrappedResponseAfterForward boolean attribute on Context to control the
bahavior, defaulting to false. (remm) \+ Fix: 68721: Workaround a possible cause
of duplicate class definitions when using ClassFileTransformers and the
transformation of a class also triggers the loading of the same class. (markt)
\+ Fix: The rewrite valve should not do a rewrite if the output is identical to
the input. (remm) \+ Update: Add a new valveSkip (or VS) rule flag to the
rewrite valve to allow skipping over the next valve in the Catalina pipeline.
(remm) \+ Update: Add highConcurrencyStatus attribute to the SemaphoreValve to
optionally allow the valve to return an error status code to the client when a
permit cannot be acquired from the semaphore. (remm) \+ Add: Add checking of the
"age" of the running Tomcat instance since its build-date to the
SecurityListener, and log a warning if the server is old. (schultz) \+ Fix: When
using the AsyncContext, throw an IllegalStateException, rather than allowing an
NullPointerException, if an attempt is made to use the AsyncContext after it has
been recycled. (markt) \+ Fix: Correct JPMS and OSGi meta-data for tomcat-embed-
core.jar by removing reference to org.apache.catalina.ssi package that is no
longer included in the JAR. Based on pull request #684 by Jendrik Johannes.
(markt) \+ Fix: Fix ServiceBindingPropertySource so that trailing \r\n sequences
are correctly removed from files containing property values when configured to
do so. Bug identified by Coverity Scan. (markt) \+ Add: Add improvements to the
CSRF prevention filter including the ability to skip adding nonces for resource
name and subtree URL patterns. (schultz) \+ Fix: Review usage of debug logging
and downgrade trace or data dumping operations from debug level to trace. (remm)
\+ Fix: 68089: Further improve the performance of request attribute access for
ApplicationHttpRequest and ApplicationRequest. (markt) \+ Fix: 68559: Allow
asynchronous error handling to write to the response after an error during
asynchronous processing. (markt) * Coyote \+ Fix: Improve the HTTP/2 stream
prioritisation process. If a stream uses all of the connection windows and still
has content to write, it will now be added to the backlog immediately rather
than waiting until the write attempt for the remaining content. (markt) \+ Fix:
Add threadsMaxIdleTime attribute to the endpoint, to allow configuring the
amount of time before an internal executor will scale back to the configured
minSpareThreads size. (remm) \+ Fix: Correct a regression in the support for
user provided SSLContext instances that broke the
org.apache.catalina.security.TLSCertificateReloadListener. (markt) \+ Fix:
Setting a null value for a cookie attribute should remove the attribute. (markt)
\+ Fix: Make asynchronous error handling more robust. Ensure that once a
connection is marked to be closed, further asynchronous processing cannot change
that. (markt) \+ Fix: Make asynchronous error handling more robust. Ensure that
once the call to AsyncListener.onError() has returned to the container, only
container threads can access the AsyncContext. This protects against various
race conditions that woudl otherwise occur if application threads continued to
access the AsyncContext. \+ Fix: Review usage of debug logging and downgrade
trace or data dumping operations from debug level to trace. In particular, most
of the HTTP/2 debug logging has been changed to trace level. (remm) \+ Fix: Add
support for user provided SSLContext instances configured on
SSLHostConfigCertificate instances. Based on pull request #673 provided by Hakan
Altındağ. (markt) \+ Fix: Partial fix for 68558: Cache the result of converting
to String for request URI, HTTP header names and the request Content-Type value
to improve performance by reducing repeated byte[] to String conversions.
(markt) \+ Fix: Improve error reporting to HTTP/2 clients for header processing
errors by reporting problems at the end of the frame where the error was
detected rather than at the end of the headers. (markt) \+ Fix: Remove the
remaining reference to a stream once the stream has been recycled. This makes
the stream eligible for garbage collection earlier and thereby improves
scalability. (markt) * Jasper \+ Add: Add support for specifying Java 22 (with
the value 22) 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 used. (markt) \+ Fix: Handle the
case where the JSP engine forwards a request/response to a Servlet that uses an
OutputStream rather than a Writer. This was triggering an IllegalStateException
on code paths where there was a subsequent attempt to obtain a Writer. (markt)
\+ Fix: Correctly handle the case where a tag library is packaged in a JAR file
and the web application is deployed as a WAR file rather than an unpacked
directory. (markt) \+ Fix: 68546: Generate optimal size and types for JSP
imports maps, as suggested by John Engebretson. (remm) \+ Fix: Review usage of
debug logging and downgrade trace or data dumping operations from debug level to
trace. (remm) * Cluster \+ Fix: Avoid updating request count stats on async.
(remm) * WebSocket \+ Fix: Correct a regression in the fix for 66508 that could
cause an UpgradeProcessor leak in some circumstances. (markt) \+ Fix: Review
usage of debug logging and downgrade trace or data dumping operations from debug
level to trace. (remm) \+ Fix: Ensure that WebSocket connection closure
completes if the connection is closed when the server side has used the
proprietary suspend/resume feature to suspend the connection. (markt) * Web
applications Add: Add support for responses in JSON format from the examples
application RequestHeaderExample. (schultz) * Other \+ Add: Improvements to
French translations. (remm) \+ Add: Improvements to Japanese translations by
tak7iji. (markt) \+ Fix: 57130: Allow digest.(sh|bat) to accept password from a
file or stdin. (csutherl/schultz) \+ Update: Update Checkstyle to 10.14.1.
(markt) \+ Fix: Correct the remaining OSGi contract references in the manifest
files to refer to the Jakarta EE contract names rather than the Java EE contract
names. Based on pull request #685 provided by Paul A. Nicolucci. (markt) \+
Update: Update Checkstyle to 10.13.0. (markt) \+ Update: Update JSign to 6.0.
(markt) \+ Update: Update the packaged version of the Tomcat Migration Tool for
Jakarta EE to 1.0.7. (markt) \+ Update: Update Tomcat Native to 2.0.7. (markt)
\+ Update: Add strings for debug level messages. (remm) \+ Add: Improvements to
French translations. (remm) \+ Add: Improvements to Japanese translations by
tak7iji. (markt)
