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 through 11.0.0, from 10.1.0 through 10.1.24, from 9.0.0 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, 10.1.25 or 9.0.90, which fixes the issue.","affected":[{"package":{"name":"tomcat","ecosystem":"Bitnami","purl":"pkg:bitnami/tomcat"},"ranges":[{"type":"SEMVER","events":[{"introduced":"9.0.0"},{"fixed":"9.0.90"},{"introduced":"10.0.0"},{"fixed":"10.1.25"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/tomcat/BIT-tomcat-2024-34750.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}],"references":[{"type":"ADVISORY","url":"https://lists.apache.org/thread/4kqf0bc9gxymjc2x7v3p7dvplnl77y8l"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-34750"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20240816-0004/"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/07/msg00009.html"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/2344a4c0d03e307ba6b8ab6dc8b894cc8bac63f2"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/2afae300c9ac9c0e516e2e9de580847d925365c3"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/9fec9a82887853402833a80b584e3762c7423f5f"}],"database_specific":{"cpes":["cpe:2.3:a:apache:tomcat:*:*:*:*:*:maven:*:*"],"severity":"High"}}
