SUSE-SU-2026:3088-1

This update for tomcat fixes the following issues

Update to Tomcat 9.0.119.

Security issues fixed:

• CVE-2026-50229: improper neutralization of script-related HTML tags in the number guess example (bsc#1269791).
• CVE-2026-53404: always-incorrect control flow implementation in the rewrite valve caused non-OR conditions to be skipped if the first condition in an OR chain matched (bsc#1269910).
• CVE-2026-53434: error condition not handled when configuring CRLs for a FFM based connector (bsc#1269824).
• CVE-2026-55276: always-incorrect control flow implementation caused special roles and empty authorization constraints to not be included when the effective web.xml was logged (bsc#1269909).
• CVE-2026-55955: improper authentication allows a replay attack against the EncryptionInterceptor in the cluster component (bsc#1269908).
• CVE-2026-55956: improper authorization leads to security constraints specified for the default servlet ignoring any method or method omission configured as part of the constraint (bsc#1269907).

    • Fix: 70049: Align the web application class loader with parent class loaders and swallow any errors caused by invalid paths when looking up resources and behave as if the resources were not found in that case. (markt)
    • Fix: Improve validation of Range and Content-Range parsers so invalid ranges trigger a 4xx response rather than a 500 response. Pull request #1012 provided by Sahana Surendra Bogar. (markt)

    • Fix: Avoid a NoClassDefFoundError at startup when catalina-tribes.jar is removed but catalina-ha.jar is present and the Cluster element is enabled in server.xml. Cluster digester rules are now fully conditional on both JARs being available. (dsoumis)

    • Fix: Add jakarta., org.apache.catalina. and org.apache.tomcat.to the list of reserved prefixes for SSI variables and request attributes. (markt)
    • Fix: Missing URL decoding when processing addMapping on a Servlet registration. (remm)

    • Add: Log a suitable warning if an encrypted PEM file is detected using an insecure form for encryption. (markt)
    • Fix: If TLS groups have been configured, use the configured groups rather than using OpenSSL's default TLS groups when using Tomcat Native with OpenSSL based connectors. (markt)
    • Fix: For HTTP/2, ensure that any in progress request body reads are cancelled if the container resets the associated stream. This prevents delays waiting for reads to time out when it is known that no more data will be received. (markt)

    • Fix: isTrailerFieldsReady was always returning true. (remm)
    • Fix: Align OpenSSL/Panama TLS implementation with other implementations and throw an exception if there is an error loading the provided CRL(s). (markt)
    • Fix: Parsing of OpenSSL format cipher expressions incorrectly stopped if @STRENGTH was encountered, ignoring any subsequent expressions. (markt)
    • Fix: Handle the case where the HTTP/2 payload length is insufficient for the mandatory data required by the flags set in the header. (markt)
    • Fix: 70102: Correct expected size of ticket keys when calling setSessionTicketKeys with an FFM connector. (markt)
