Changes for libtcnative-1-0:
- Update to 1.3.9
* Security fixes
+ Client certificate requirements can be down-graded
(bsc#1282621, CVE-2026-86247)
A race condition allowed client certificate verification
requirements to be down-graded for some configurations.
+ Insecure OpenSSL options enabled (bsc#1282622, CVE-2026-86246)
Apache Tomcat Native enabled insecure options by default
including ALLOW_CLIENT_RENEGOTIATION,
NO_EXTENDED_MASTER_SECRET, IGNORE_UNEXPECTED_EOF and
ALLOW_NO_DHE_KEX.
+ DoS via TLS handshake (bsc#1282623, CVE-2026-86243)
A buffer over-read vulnerability in Apache Tomcat Native
during the TLS handshaking permits a malicious user to trigger
a DoS via a JVM crash.
* Changes
+ Code: Remove call to ERR_remove_thread_state() from Windows
specific code to allow building with OpenSSL 4.0.x.
ERR_remove_thread_state() is a no-op in OpenSSL 1.1+ and got
removed in OpenSSL 4
+ Fix: Fix a potential crash when negotiating ALPN
+ If ALPN negotiation fails and failure is configured to use
the last server protocol in the list, use it rather than the
last protocol offered by the client
+ Fix: Add support for the extended range of options available
from OpenSSL 3.0.x. The options flag is now a 64-bit unsigned
int (represented by a Java long) rather than a 32-bit unsigned
int (represented by a Java int)
+ Code: Remove unused code
+ Ensure that per connection changes to certificate verification
settings, e.g. to support client certificate authentication,
do not modify the certificate verification settings for other
connections
+ Fix: Fix a potential crash when configuring raw certificates
+ Fix: Avoid a potential crash with very long ALPN protocol
names
+ Fix: Make the call to a CertificateVerifier more robust
+ Fix: Avoid a potential crash when processing OCSP URLs
+ Fix: Make the processing of OCSP responses more robust
+ Fix: Stricter OCSP handling when soft-fail is disabled
+ Fix: Harden against the mis-use of Buffer.address(ByteBuffer)
+ Fix: Harden against the mis-use of Pool.destroy(long)
+ Code: The minimum supported OpenSSL version is now 3.0.x.
OpenSSL 1.1.1 support was accidentally broken in 1.3.8. As no
bug reports were receive for that failure and since both
Debian and Ubuntu versions that used OpenSSL 1.1.1 have
reached end of support, OpenSSL 1.1.1 is no longer supported
+ Update: OpenSSL 3.0.x is approaching end of support so the
recommended version of OpenSSL (and the version that windows
binaries will be built with) now follows the 3.5.x LTS branch
+ Fix: Switch to automatic configuration of DH parameters.
Manual configuration attempts will be ignored
+ Code: Make setTmpECDHByCurveName() a NO-OP
+ Fix: Refactor extraction of ECDH curve name from the
Certificate to avoid deprecated OpenSSL methods
+ Fix: Refactor the native implementation of SSL.getTime() to
avoid the Y2038 problem in SSL_SESSION_get_time() when running
on a verion of OpenSSL that includes the new
SSL_SESSION_get_time_ex() method
Changes for tomcat11:
- Update to Tomcat 11.0.26
* Catalina
+ Fix: Improve the handling of AsyncContext.dispatch() when the Context
attribute dispatchersUseEncodedPaths is set to false since the
application has no control over the path used for the
AsyncContext.dispatch(). Prior to this fix, paths containing literal '?'
characters were truncated. (markt)
+ Fix: Ensure that capture groups from a RewriteCond always reflect the
result of the current request. (markt)
+ Fix: When a PersistentManager needs to reduce the number of active
sessions, swap out the least recently used eligible sessions first. Pull
request #1045 provided by sainadh777. (markt)
+ Fix: Align web.xml logging output with the new Context attribute
urlPatternsProvidedInDecodedForm. (markt)
+ Fix: Improve robustness of DIGEST authentication to system clock jumps.
(markt)
+ Add: Support multiple protocol header values (treat as a single merged
header value) in the RemoteIpFilter and RemoteIpValve. (markt)
+ Fix: potential concurrency issues when loading/saving sessions from/to a
session store. Custom Store implementations that do not extend StoreBase
must implement the new getSessionStoreLock() method of the Store
interface to ensure concurrency protection. The default method
implementation provided only provides the pre-fix functionality. (markt)
+ Fix: Ensure that PersistentManager implementations that extend
PersistentManagerBase do not swap out sessions that are associated with
a request that is currently being processed. This includes not swapping
out a session unless the session was created when activity tracking was
enabled. (markt)
+ Fix: Ensure namespace attributes are XML escaped in WebDAV responses.
+ Fix: Resolve null or missing rewrite substitutions as an empty string,
to align with the mod_rewrite behavior. (remm)
+ Add: a best efforts protection in the CrawlerSessionManagerValve against
crawlers being associated with an authenticated session. (markt)
+ Fix: Clarify the meaning of various RewriteValve server variables and
explicitly use the canonical context path for the CONTEXT_PATH server
variable. (markt)
+ Fix: storeconfig not saving the path when a context is saved in
server.xml. (remm)
+ Fix: WAR URLConnection should propagate use of caching. (remm)
+ Fix: Ensure resources are evicted from the static resource cache in the
correct order. (markt)
+ Fix: When Jakarta Authentication is configured for a web application,
cache the ServerAuthConfig in the Authenticator valve. This ensures web
application specific settings are cached on a per web application basis.
+ Fix: 70203: Fix RegistrationListener notifications in Jakarta
Authentication implementation. (markt)
+ Fix: Handle CGI scripts that write excessively to stdout after setting
an HTTP error status code. (schultz)
+ Fix: Require the request to the login action during FORM authentication
to be made using HTTP POST. (markt)
+ Fix: 70208: Make URL encoding more robust. Based on pull request #1065
by Chenjp. (markt)
* Coyote
+ Fix: parsing of client certificates that specify more than one OCSP
responder for configurations that use OpenSSL-FFM. (markt)
+ Fix: xreflection generated code stack overflow issue. (remm)
+ Fix: Align xreflection better with IntrospectionUtils. (remm)
+ Fix: In HTTP/2 after half closed (remote), any unexpected frame should
be a stream error. (remm)
+ Fix: incorrect initial window size calculation when upgrading to HTTP/2.
(remm)
+ Fix: Avoid HTTP/2 exceptions with invalid content-length values. (remm)
+ Fix: Only try and load the native library from the CATALINA_HOME system
property when the property is set. (markt)
+ Fix: max connections enforcement after an enpoint resume. (remm)
+ Fix: Implement stricter ALPN matching for Connectors using FFM. (markt)
+ Add: length validation for ALPN protocol names. (markt)
+ Fix: Make FFM certificate verification more robust. (markt)
+ Fix: Align FFM OCSP URL parsing with Tomcat Native and treat a parsing
failure as if no usable OCSP URLs were present. (markt)
+ Fix: Make the processing of OCSP responses more robust. (markt)
+ Fix: Stricter OCSP handling when soft-fail is disabled. (markt)
+ Fix: Cleaner handling of AJP response headers which overflow the maximum
message size. (remm)
+ Fix: Small per performance optimisation. Don't waste cycles swallowing
an AJP response body when the connection is going to be closed. (markt)
+ Fix: OpenSSL support for CRLs when using OpenSSL trust with the server
key held in a Java key store. (markt)
+ Fix: Reject HTTP/1.0 or earlier requests that send a transfer-encoding
header. (markt)
+ Fix: Ensure per request HTTP/2 bad request marker is cleared when the
request is recycled. (markt)
+ Fix: Additional clean-up after HTTP/2 stream reset to aid GC. (markt)
+ Fix: Revert earlier refactoring of HTTP/2 header field validation that
moved it earlier since the refactoring made correct handling of invalid
headers more difficult. (markt)
* Jasper
+ Fix: EL evaluation of some lambda expressions. (remm)
* WebSocket
+ Fix: an exception when an automatic Pong response races with the closing
of the WebSocket session. (moritzfl)
+ Fix: Harden the WebSocket client and use a SecureRandom when generating
the Sec-WebSocket-Key header. (markt)
+ Fix: Improve robustness of client handshakes. (remm)
+ Fix: Ensure that WebSocket write timeouts apply to the complete message
and are not lost if two writes have the same timeout. (markt)
+ Fix: Reduce CPU usage while sending WebSocket close message. (markt)
+ Fix: overly broad check that prevented request URIs containing literal {
and } characters from being mapped to WebSocket end points. (markt)
+ Fix: handling of WebSocket messages with compressed payloads using per-
message-deflate that have one or more non-final blocks where the BFINAL
bit is set. (markt)
+ Fix: handling of per-message-deflate context takeover when receiving
compressed WebSocket messages. (markt)
* Web applications
+ Fix: Manager: Fix a potential concurrency issue when ordering sessions
prior to displaying a list of session. (markt)
+ Docs: Wrap the RewriteRule regular expression syntax reference on narrow
displays. Pull request #1044 by sainadh777. (markt)
* Other
+ Update: Easymock to 5.7.0. (markt)
+ Update: bnd to 7.4.0. (markt)

+ Add: Improvements to French translations. (remm)
+ Add: Improvements to Japanese translations provided by tak7iji and
Ktamura.biz.80. (markt)
* Cluster
+ Fix: Validate that the DeltaManager attribute sendAllSessionsSize is a
positive integer. Zero or negative values previously caused an infinite
loop or a NegativeArraySizeException during session state transfer. Pull
request #1042 provided by lihongyi87. (markt)
+ Fix: Improve robustness of cloud membership providers if an error occurs
fetching members. (remm)
* jdbc-pool
+ Fix: DataSourceProxy.getPooledConnection(String,String) now delegates to
getConnection(String,String) rather than getConnection(). (markt)
+ Add: Log a warning if an attempt is made to obtain a connection with
credentials when alternateUsernameAllowed is set to false. (markt)
+ Fix: Ensure StatementCache interceptor resets properties of cached
statements between uses. (mark)CVSSUnscoredInsufficient evidenceSUSE-SU-2026:4114-1SUSE Linux Enterprisesuse · tomcat11&distro=SUSE Linux Enterprise Module for Web and Scripting 15 SP7 +2 moresuse tomcat11&distro=SUSE Linux Enterprise Module for Web and Scripting 15 SP7Security update for tomcat11

This update for tomcat11 fixes the following issues
Update to Tomcat 11.0.22:
- CVE-2026-41284: Unbounded read in WebDAV LOCK and PROPFIND handling (bsc#1265162).
- CVE-2026-41293: HTTP/2 request headers not validated (bsc#1265163).
- CVE-2026-42498: WebSocket authentication header exposure (bsc#1265165).
- CVE-2026-43512: digest authenticator will authenticate any unknown user (bsc#1265145).
- CVE-2026-43513: LockOutRealm treats user names as case-sensitive (bsc#1265166).
- CVE-2026-43514: AJP secret compared in non-constant time (bsc#1265167).
- CVE-2026-43515: Security constraints not correctly applied (bsc#1265168).
Changes:
* Catalina
+ Add: Enhance version.sh and version.bat to display APR, Tomcat Native, and
OpenSSL version information (both APR and FFM implementations), along with
version compatibility warnings and third-party library version
information. (csutherl)
+ Code: Refactor generation of the remote user element in the access log to
remove unnecessary code. (markt)
+ Fix: Fix a regression in the previous release that meant ?- could appear
in the access log rather than ? when the query string was present but
empty. (markt)
+ Fix: Failed precondition should make WebDAV DELETE fail. #982 submitted by
Mahmoud Alarby. (remm)
+ Fix: Align the escaping in ExtendedAccessLogValve with the other
AccessLogValve implementations. (markt)
+ Fix: 70000: fix duplication of special headers in the response after
commit, following fix for 69967. (remm)
+ Fix: Correct the handling of URIs mapped to a security constraint that
only specifies the special ** role for all authenticated users. Requests
without authentication were receiving 403 responses rather than 401
responses. (markt)
+ Fix: Fix a race condition in StandardContext.getServletContext() that
could cause the jakarta.servlet.context.tempdir attribute to be lost
during a context reload. Make the context field volatile and use locking
to ensure only one ApplicationContext instance is created. (dsoumis)
+ Fix: Update the Windows authentication (kerberos) documentation to reflect
that both Java and Windows are removing / have removed support for
RC4-HMAC. The guide now uses AES256-SHA1. (markt)
+ Fix: Add a new initialisation parameter for WebDAV, maxRequestBodySize
which limits the size of a WebDAV request body for LOCK and PROPFIND. The
default value is 4096 bytes. (markt)
+ Add: Add a new caseSensitive attribute to the LockOutRealm that controls
the manner in which user names are treated when making locking decisions.
The default is false, meaning user names are treated in a case insensitive
manner. (markt)
+ Fix: Correct the handling of invalid users with DIGEST authentication.
(markt)
+ Fix: Ensure RealmBase finds all matching extension based security
constraints. (markt)
* Coyote
+ Fix: Avoid various edge cases if Content-Length is set via
setHeader(String,String) or addHeader(String,String) with an invalid value
by always clearing the previous value whether the new value is valid or
not and ignoring any invalid new value. (markt)
+ Code: Refactor the calculation of the real index in the HPACK dynamic
header table implementation to reduce code duplication. (markt)
+ Fix: Fix various minor issues with some HTTP/2 stream error messages for
HTTP/2. (markt)
+ Fix: Consistently reject URIs containing NULL bytes when normalizing.
+ Fix: Fix a few minor memory leaks on error paths reading TLS keys and
certificates when using FFM. (markt)
+ Fix: Refactor clean-up after HTTP/2 headers have been processed to aid GC
after a stream reset. (markt)
+ Fix: Align HTTP/2 trailer fields with HTTP/1.1 and filter out any fields
not permitted in trailers. (markt)
+ Fix: Free private keys after use in FFM based connector configuration.
+ Fix: Correct an unlikely edge-case parsing bug in the HTTP/2 HPACK header
decoding that could result in a valid header triggering an unexpected
connection close. (markt)
+ Fix: Refactor HTTP/2 HPACK encoding so header field names are only
converted to lower case once during the encoding process. (markt)
+ Fix: Refactor HTTP/2 header field validation so it occurs earlier. Extend
validation to check for disallowed characters as well as upper case
characters. (markt)
+ Fix: Add TLS 1.3 groups added in OpenSSL 4.0. (remm)
+ Fix: Add validation that the HTTP/2 :scheme pseudo-header is consistent
with the use (or not) of TLS. (markt)
+ Fix: Correct the validation of pseudo headers and CONNECT requests to
align Tomcat's behaviour with RFC 9113, section 8.5. (markt)
+ Fix: Fix a potential integer overflow when allocating capacity from a
connection level window update to individual HTTP/2 streams. Based on #996
by Mike Tingey Jr. (markt)
+ Fix: Switch AJP secret comparison to a constant time algorithm. (markt)
* WebSocket
+ Fix: Fix the initial connection to a WebSocket end point where the
connection is made via a proxy that requires DIGEST authentication.
* Other
+ Fix: 69993: Update the URL to the CDDL 1.0 license. (markt)
+ Add: Add warning when OpenSSL binary is not found. (csutherl)
+ Add: Add check for Tomcat Native library, and log warning when it's not
found to make it easier to see when it's not used by the suite. (csutherl)
+ Update: Update Byte Buddy to 1.18.8. (markt)
+ Update: Update Bouncy Castle to 1.84. (markt)
+ Update: Improvements to French translations. (remm)
+ Update: Improvements to Japanese translations provided by tak7iji.
