Description:

This update for tomcat11 fixes the following issues:

Update to Tomcat 11.0.18:

  • CVE-2025-66614: client certificate verification bypass due to virtual host mapping (bsc#1258371).
  • CVE-2026-24733: improper input validation on HTTP/0.9 requests (bsc#1258385).
  • CVE-2026-24734: certificate revocation bypass due to incomplete OCSP verification checks (bsc#1258387).

Changelog:

  • Catalina
  • Fix: 69932: Fix request end access log pattern regression, which would log the start time of the request instead. (remm)
  • Fix: 69623: Additional fix for the long standing regression that meant that calls to ClassLoader.getResource().getContent() failed when made from within a web application with resource caching enabled if the target resource was packaged in a JAR file. (markt)
  • Fix: Pull request #923: Avoid adding multiple CSRF tokens to a URL in the CsrfPreventionFilter. (schultz)
  • Fix: 69918: Ensure request parameters are correctly parsed for HTTP/2 requests when the content-length header is not set. (dsoumis)
  • Update: Enable minimum and recommended Tomcat Native versions to be set separately for Tomcat Native 1.x and 2.x. Update the minimum and recommended versions for Tomcat Native 1.x to 1.3.4. Update the minimum and recommended versions for Tomcat Native 2.x to 2.0.12. (markt)
  • Add: Add a new ssoReauthenticationMode to the Tomcat provided Authenticators that provides a per Authenticator override of the SSO Valve requireReauthentication attribute. (markt)
  • Fix: Ensure URL encoding errors in the Rewrite Valve trigger an exception rather than silently using a replacement character. (markt)
  • Fix: 69871: Increase log level to INFO for missing configuration for the rewrite valve. (remm)
  • Fix: Add log warnings for additional Host appBase suspicious values. (remm)
  • Fix: Remove hard dependency on tomcat-jni.jar for catalina.jar. org.apache.catalina.Connector no longer requires org.apache.tomcat.jni.AprStatus to be present. (markt)
  • Add: Add the ability to use a custom function to generate the client identifier in the CrawlerSessionManagerValve. This is only available programmatically. Pull request #902 by Brian Matzon. (markt)
  • Fix: Change the SSO reauthentication behaviour for SPNEGO authentication so that a normal SPNEGO authentication is performed if the SSL Valve is configured with reauthentication enabled. This is so that the delegated credentials will be available to the web application. (markt)
  • Fix: When generating the class path in the Loader, re-order the check on individual class path components to avoid a potential NullPointerException. Identified by Coverity Scan. (markt)
  • Fix: Fix SSL socket factory configuration in the JNDI realm. Based on pull request #915 by Joshua Rogers. (remm)
  • Update: Add an attribute, digestInRfc3112Order, to MessageDigestCredentialHandler to control the order in which the credential and salt are digested. By default, the current, non-RFC 3112 compliant, order of salt then credential will be used. This default will change in Tomcat 12 to the RFC 3112 compliant order of credential then salt. (markt)
  • Cluster
  • Add: 62814: Document that human-readable names may be used for mapSendOptions and align documentation with channelSendOptions. Based on pull request #929 by archan0621. (markt)
  • Clustering
  • Fix: Correct a regression introduced in 11.0.11 that broke some clustering configurations. (markt)
  • Coyote
  • Fix: 69936: Fix bug in previous fix for Tomcat Native crashes on shutdown that triggered a significant memory leak. Patch provided by Wes. (markt)
  • Fix: Prevent concurrent release of OpenSSLEngine resources and the termination of the Tomcat Native library as it can cause crashes during Tomcat shutdown. (markt)
  • Fix: Improve warnings when setting ciphers lists in the FFM code, mirroring the tomcat-native changes. (remm)
  • Fix: 69910: Dereference TLS objects right after closing a socket to improve memory efficiency. (remm)
  • Fix: Relax the JSSE vs OpenSSL configuration style checks on SSLHostConfig to reflect the existing implementation that allows one configuration style to be used for the trust attributes and a different style for all the other attributes. (markt)
  • Fix: Better warning message when OpenSSLConf configuration elements are used with a JSSE TLS implementation. (markt)
  • Fix: When using OpenSSL via FFM, don't log a warning about missing CA certificates unless CA certificates were configured and the configuration failed. (markt)
  • Add: For configuration consistency between OpenSSL and JSSE TLS implementations, TLSv1.3 cipher suites included in the ciphers attribute of an SSLHostConfig are now always ignored (previously they would be ignored with OpenSSL implementations and used with JSSE implementations) and a warning is logged that the cipher suite has been ignored. (markt)
  • Add: Add the ciphersuite attribute to SSLHostConfig to configure the TLSv1.3 cipher suites. (markt)
  • Add: Add OCSP support to JSSE based TLS connectors and make the use of OCSP configurable per connector for both JSSE and OpenSSL based TLS implementations. Align the checks performed by OpenSSL with those performed by JSSE. (markt)
  • Add: Add support for soft failure of OCSP checks with soft failure support disabled by default. (markt)
  • Add: Add support for configuring the verification flags passed to OCSP_basic_verify when using an OpenSSL based TLS implementation. (markt)
  • Fix: Fix OpenSSL FFM code compatibility with LibreSSL versions below 3.5.
  • Fix: Don't log an incorrect certificate KeyStore location when creating a TLS connector if the KeyStore instance has been set directly on the connector. (markt)
  • Fix: HTTP/0.9 only allows GET as the HTTP method. (remm)
  • Add: Add strictSni attribute on the Connector to allow matching the SSLHostConfig configuration associated with the SNI host name to the SSLHostConfig configuration matched from the HTTP protocol host name. Non matching configurations will cause the request to be rejected. The attribute default value is true, enabling the matching. (remm)
  • Fix: Graceful failure for OCSP on BoringSSL in the FFM code. (remm)
  • Fix: 69866: Fix a memory leak when using a trust store with the OpenSSL provider. Pull request #912 by aogburn. (markt)
  • Fix: Fix potential crash on shutdown when a Connector depends on the Tomcat Native library. (markt)
  • Fix: Fix AJP message length check. Pull request #916 by Joshua Rogers.
  • Jasper
  • Fix: 69333: Correct a regression in the previous fix for 69333 and ensure that reuse() or release() is always called for a tag. (markt)
  • Fix: 69877: Catch IllegalArgumentException when processing URIs when creating the classpath to handle invalid URIs. (remm)
  • Fix: Fix populating the classpath with the webapp classloader repositories. (remm)
  • Fix: 69862: Avoid NPE unwrapping Servlet exception which would hide some exception details. Patch submitted by Eric Blanquer. (remm)
  • Jdbc-pool
  • Fix: 64083: If the underlying connection has been closed, don't add it to the pool when it is returned. Pull request #235 by Alex Panchenko. (markt)
  • Web applications
  • Fix: Manager: Fix abrupt truncation of the HTML and JSON complete server status output if one or more of the web applications failed to start. (schultz)
  • Add: Manager: Include web application state in the HTML and JSON complete server status output. (markt)
  • Add: Documentation: Expand the documentation to better explain when OCSP is supported and when it is not. (markt)
  • Websocket
  • Fix: 69920: When attempting to write to a closed Writer or OutputStream obtained from a WebSocket session, throw an IOException rather than an IllegalStateExcpetion as required by Writer and strongly suggested by OutputStream. (markt)
  • Other
  • Add: Add property "gpg.sign.files" to optionally disable release artefact signing with GPG. (rjung)
  • Add: Add test.silent property to suppress JUnit console output during test execution. Useful for cleaner console output when running tests with multiple threads. (csutherl)

  • Update: Update the internal fork of Commons DBCP to 2.14.0. (markt)
