Fix of 7 CVEs
Details
  • SECURITY UPDATE: multiple security fixes
    • debian/patches/CVE-2026-41284.patch: add a configurable maxRequestBodySize init-param to the WebDAV servlet to bound LOCK/PROPFIND XML request bodies; reject oversized bodies with 413 Request Entity Too Long. Includes the upstream BoundedByteArrayOutputStream helper and associated tests

    • debian/patches/CVE-2026-41293.patch: filter invalid HTTP/2 header names in HpackDecoder / HPackHuffman / Stream / Http2Parser using a new HttpParser.isToken-based check; folds upstream follow-up (HttpParser i>32 hex/decimal fix, additional LocalStrings keys, HpackHuffman field-name branch simplification) and ships the new TestHPackHuffman / TestHttp2Section82 tests.
    • debian/patches/CVE-2026-41293-tests.patch: adapt TestHttp2Section82 to the 9.0.31 readFrame(boolean) signature

    • debian/patches/CVE-2026-43514.patch: switch the AJP secret comparison in AjpProcessor to a constant-time comparison using the new ConstantTime utility; includes the upstream ByteChunk start-offset follow-up
