The target Jetty 11.0.28 does not contain the CVE-2023-36478 integer overflow vulnerability. The vulnerable checkSize method that allowed integer overflow when multiplying header lengths by 4/3 for huffman encoding was removed in upstream commit c7a4b05fc73 (September 2023) before TuxCare onboarded version 11.0.26. The fix was authored by Lachlan Roberts (Webtide/Jetty upstream), not TuxCare. The target has defensive code including: (1) negative integer check in HpackDecoder.integerDecode, (2) Math.addExact/multiplyExact in NBitIntegerDecoder to prevent overflow, (3) safe size validation in MetaDataBuilder.emit without the problematic huffman fudge factor multiplication.\n\nAdvisory cross-check (dlmn): outside the affected ranges of GitHub (>= 10.0.0, < 10.0.16; >= 11.0.0, < 11.0.16; >= 10.0.0, < 10.0.16; >= 11.0.0, < 11.0.16; >= 9.3.0, < 9.4.53), NVD (>= 9.3.0, < 9.4.53; >= 10.0.0, < 10.0.16; >= 11.0.0, < 11.0.16), cve.org (>= 10.0.0, < 10.0.16; >= 11.0.0, < 11.0.16; >= 9.3.0, < 9.4.53), Snyk (>= 9.3.0, < 9.4.53.v20231009; >= 10.0.0, < 10.0.16; >= 11.0.0, < 11.0.16; >= 10.0.0, < 10.0.16; >= 11.0.0, < 11.0.16; >= 9.3.0, < 9.4.53.v20231009; >= 10.0.0, < 10.0.16; >= 11.0.0, < 11.0.16).",
