{"id":"GHSA-wph7-x527-w3h5","summary":"Missing Release of Resource after Effective Lifetime in Apache Tomcat","details":"The fix for bug 63362 present in Apache Tomcat 10.1.0-M1 to 10.1.0-M5, 10.0.0-M1 to 10.0.11, 9.0.40 to 9.0.53 and 8.5.60 to 8.5.71 introduced a memory leak. The object introduced to collect metrics for HTTP upgrade connections was not released for WebSocket connections once the connection was closed. This created a memory leak that, over time, could lead to a denial of service via an OutOfMemoryError.","aliases":["BIT-tomcat-2021-42340","CVE-2021-42340"],"modified":"2024-03-11T16:46:09.168126Z","published":"2021-10-15T18:51:34Z","database_specific":{"github_reviewed_at":"2021-10-15T13:59:01Z","nvd_published_at":"2021-10-14T20:15:00Z","cwe_ids":["CWE-772"],"severity":"HIGH","github_reviewed":true},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-42340"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/31d62426645824bdfe076a0c0eafa904d90b4fb9"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/80f1438ec45e77a07b96419808971838d259eb47"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/d27535bdee95d252418201eb21e9d29476aa6b6a"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/d5a6660cba7f51589468937bf3bbad4db7810371"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpujul2022.html"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpujan2022.html"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpuapr2022.html"},{"type":"WEB","url":"https://www.debian.org/security/2021/dsa-5009"},{"type":"WEB","url":"https://tomcat.apache.org/security-9.html"},{"type":"WEB","url":"https://tomcat.apache.org/security-8.html"},{"type":"WEB","url":"https://tomcat.apache.org/security-10.html"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20211104-0001"},{"type":"WEB","url":"https://security.gentoo.org/glsa/202208-34"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r83a35be60f06aca2065f188ee542b9099695d57ced2e70e0885f905c%40%3Cannounce.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r8097a2d1550aa78e585fc77e602b9046e6d4099d8d132497c5387784@%3Ccommits.myfaces.apache.org%3E"},{"type":"WEB","url":"https://kc.mcafee.com/corporate/index?page=content&id=SB10379"},{"type":"PACKAGE","url":"https://github.com/apache/tomcat"}],"affected":[{"package":{"name":"org.apache.tomcat:tomcat","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat/tomcat"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"10.1.0-M1"},{"fixed":"10.1.0-M6"}]}],"versions":["10.1.0-M1","10.1.0-M2","10.1.0-M4","10.1.0-M5"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/10/GHSA-wph7-x527-w3h5/GHSA-wph7-x527-w3h5.json","last_known_affected_version_range":"\u003c= 10.1.0-M5"}},{"package":{"name":"org.apache.tomcat:tomcat","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat/tomcat"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"10.0.0-M1"},{"fixed":"10.0.12"}]}],"versions":["10.0.0","10.0.0-M1","10.0.0-M10","10.0.0-M3","10.0.0-M4","10.0.0-M5","10.0.0-M6","10.0.0-M7","10.0.0-M8","10.0.0-M9","10.0.10","10.0.11","10.0.2","10.0.4","10.0.5","10.0.6","10.0.7","10.0.8"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/10/GHSA-wph7-x527-w3h5/GHSA-wph7-x527-w3h5.json"}},{"package":{"name":"org.apache.tomcat:tomcat","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat/tomcat"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.0.40"},{"fixed":"9.0.54"}]}],"versions":["9.0.40","9.0.41","9.0.43","9.0.44","9.0.45","9.0.46","9.0.48","9.0.50","9.0.52","9.0.53"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/10/GHSA-wph7-x527-w3h5/GHSA-wph7-x527-w3h5.json"}},{"package":{"name":"org.apache.tomcat:tomcat","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat/tomcat"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"8.5.60"},{"fixed":"8.5.72"}]}],"versions":["8.5.60","8.5.61","8.5.63","8.5.64","8.5.65","8.5.66","8.5.68","8.5.69","8.5.70","8.5.71"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/10/GHSA-wph7-x527-w3h5/GHSA-wph7-x527-w3h5.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
