When processing an HTTP/2 stream, Tomcat did not handle some cases of excessive HTTP headers correctly. This led to a miscounting of active HTTP/2 streams which in turn led to the use of an incorrect infinite timeout which allowed connections to remain open which should have been closed.\n\nThis issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.0-M20, from 10.1.0-M1 through 10.1.24, from 9.0.0-M1 through 9.0.89.\n\nThe following versions were EOL at the time the CVE was created but are \nknown to be affected: 8.5.0 though 8.5.100. Other EOL versions may also be affected.\n\n\nUsers are recommended to upgrade to version 11.0.0-M21, 10.1.25 or 9.0.90, which fixes the issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-400","CWE-755"],"references":["https://lists.apache.org/thread/4kqf0bc9gxymjc2x7v3p7dvplnl77y8l","https://lists.apache.org/thread/4kqf0bc9gxymjc2x7v3p7dvplnl77y8l","https://lists.debian.org/debian-lts-announce/2025/07/msg00009.html","https://security.netapp.com/advisory/ntap-20240816-0004/"],"products":["apache:tomcat","netapp:ontap_tools"],"source":"nvd","synced_at":"2026-10-19T21:52:00.836172422+00:00"},"epss":{"cve":"CVE-2024-34750","score":0.04602,"percentile":0.91668,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-wm9w-rjj3-j356","url":"https://osv.dev/vulnerability/GHSA-wm9w-rjj3-j356","summary":"Apache Tomcat - Denial of Service","modified":"2026-09-10T03:50:17.269240047Z","packages":[{"ecosystem":"Maven","name":"org.apache.tomcat.embed:tomcat-embed-core","purl":"pkg:maven/org.apache.tomcat.embed/tomcat-embed-core","ranges":[">=11.0.0-M1 <11.0.0-M21"],"fixed":["11.0.0-M21"]},{"ecosystem":"Maven","name":"org.apache.tomcat.embed:tomcat-embed-core","purl":"pkg:maven/org.apache.tomcat.embed/tomcat-embed-core","ranges":[">=10.1.0-M1 <10.1.25"],"fixed":["10.1.25"]},{"ecosystem":"Maven","name":"org.apache.tomcat.embed:tomcat-embed-core","purl":"pkg:maven/org.apache.tomcat.embed/tomcat-embed-core","ranges":[">=9.0.0-M1 <9.0.90"],"fixed":["9.0.90"]},{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat-coyote","purl":"pkg:maven/org.apache.tomcat/tomcat-coyote","ranges":[">=11.0.0-M1 <11.0.0-M21"],"fixed":["11.0.0-M21"]},{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat-coyote","purl":"pkg:maven/org.apache.tomcat/tomcat-coyote","ranges":[">=10.1.0-M1 <10.1.25"],"fixed":["10.1.25"]},{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat-coyote","purl":"pkg:maven/org.apache.tomcat/tomcat-coyote","ranges":[">=9.0.0-M1 <9.0.90"],"fixed":["9.0.90"]},{"ecosystem":"Maven","name":"org.apache.tomcat:tomcat-coyote","purl":"pkg:maven/org.apache.tomcat/tomcat-coyote","ranges":[">=8.5.0 <=8.5.100"],"fixed":[]},{"ecosystem":"Maven","name":"org.apache.tomcat.embed:tomcat-embed-core","purl":"pkg:maven/org.apache.tomcat.embed/tomcat-embed-core","ranges":[">=8.5.0 <=8.5.100"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
