In versions 11.0.0 through 11.0.15, 10.0.0 through 10.0.15, and 9.0.0 through 9.4.52, an integer overflow in `MetaDataBuilder.checkSize` allows for HTTP/2 HPACK header values to exceed their size limit. `MetaDataBuilder.java` determines if a header name or value exceeds the size limit, and throws an exception if the limit is exceeded. However, when length is very large and huffman is true, the multiplication by 4 in line 295 will overflow, and length will become negative. `(_size+length)` will now be negative, and the check on line 296 will not be triggered. Furthermore, `MetaDataBuilder.checkSize` allows for user-entered HPACK header value sizes to be negative, potentially leading to a very large buffer allocation later on when the user-entered size is multiplied by 2. This means that if a user provides a negative length value (or, more precisely, a length value which, when multiplied by the 4/3 fudge factor, is negative), and this length value is a very large positive number when multiplied by 2, then the user can cause a very large buffer to be allocated on the server. Users of HTTP/2 can be impacted by a remote denial of service attack. The issue has been fixed in versions 11.0.16, 10.0.16, and 9.4.53. There are no known workarounds.",null,[],[],[],[14],{"_key":15},"CVE-2023-36478",[],[],[],"2023-10-10T17:15:00Z","2025-10-24T05:02:07Z",{"cisa_kev":22,"cisa_ransomware":22,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":9,"severity_score":9,"severity_version":9,"severity_source":9,"severity_vector":9,"severity_status":9},false,[24,30,34,38,42,46,50],{"url":25,"sources":26,"tags":28},"https://ubuntu.com/security/CVE-2023-36478",[27],"osv_ubuntu",[29],"REPORT",{"url":31,"sources":32,"tags":33},"https://github.com/eclipse/jetty.project/pull/9634",[27],[29],{"url":35,"sources":36,"tags":37},"https://github.com/eclipse/jetty.project/releases/tag/jetty-11.0.16",[27],[29],{"url":39,"sources":40,"tags":41},"https://github.com/eclipse/jetty.project/security/advisories/GHSA-wgh7-54f2-x98r",[27],[29],{"url":43,"sources":44,"tags":45},"https://github.com/eclipse/jetty.project/releases/tag/jetty-9.4.53.v20231009",[27],[29],{"url":47,"sources":48,"tags":49},"https://github.com/eclipse/jetty.project/releases/tag/jetty-10.0.16",[27],[29],{"url":51,"sources":52,"tags":53},"https://www.cve.org/CVERecord?id=CVE-2023-36478",[27],[29],[],[],[57],{"source":27,"cvss_v2_0":9,"cvss_v3_0":9,"cvss_v3_1":58,"cvss_v4_0":9},{"baseScore":59,"baseSeverity":9,"vectorString":60,"impactScore":61,"exploitabilityScore":62},7.5,"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H",6,10,[64],{"ecosystem":65,"name":66,"vendor":67,"product":66,"cpe_part":9,"purl_type":68,"purl_namespace":67,"purl_name":66,"source":9,"versions":69},"Ubuntu","jetty","ubuntu","deb",[70,74],{"version":71,"is_range":72,"range_type":73,"version_start":9,"version_start_type":9,"version_end":9,"version_end_type":9,"fixed_in":9},"all",true,"ecosystem",{"version":71,"is_range":72,"range_type":73,"version_start":9,"version_start_type":9,"version_end":9,"version_end_type":9,"fixed_in":9}]
