While this would most likely lead to an error and the closure of the HTTP/2 connection, it is possible that information could leak between requests.","affected":[{"package":{"name":"org.apache.tomcat:tomcat-coyote","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat/tomcat-coyote"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"10.0.0-M1"},{"fixed":"10.0.0-M10"}]}],"versions":["10.0.0-M1","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"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/02/GHSA-vvw4-rfwf-p6hx/GHSA-vvw4-rfwf-p6hx.json"}},{"package":{"name":"org.apache.tomcat:tomcat-coyote","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat/tomcat-coyote"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.0.0-M1"},{"fixed":"9.0.40"}]}],"versions":["9.0.0.M1","9.0.0.M10","9.0.0.M11","9.0.0.M13","9.0.0.M15","9.0.0.M17","9.0.0.M18","9.0.0.M19","9.0.0.M20","9.0.0.M21","9.0.0.M22","9.0.0.M25","9.0.0.M26","9.0.0.M27","9.0.0.M3","9.0.0.M4","9.0.0.M6","9.0.0.M8","9.0.0.M9","9.0.1","9.0.10","9.0.11","9.0.12","9.0.13","9.0.14","9.0.16","9.0.17","9.0.19","9.0.2","9.0.20","9.0.21","9.0.22","9.0.24","9.0.26","9.0.27","9.0.29","9.0.30","9.0.31","9.0.33","9.0.34","9.0.35","9.0.36","9.0.37","9.0.38","9.0.39","9.0.4","9.0.5","9.0.6","9.0.7","9.0.8"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/02/GHSA-vvw4-rfwf-p6hx/GHSA-vvw4-rfwf-p6hx.json"}},{"package":{"name":"org.apache.tomcat:tomcat-coyote","ecosystem":"Maven","purl":"pkg:maven/org.apache.tomcat/tomcat-coyote"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"8.5.0"},{"fixed":"8.5.60"}]}],"versions":["8.5.0","8.5.11","8.5.12","8.5.13","8.5.14","8.5.15","8.5.16","8.5.19","8.5.2","8.5.20","8.5.21","8.5.23","8.5.24","8.5.27","8.5.28","8.5.29","8.5.3","8.5.30","8.5.31","8.5.32","8.5.33","8.5.34","8.5.35","8.5.37","8.5.38","8.5.39","8.5.4","8.5.40","8.5.41","8.5.42","8.5.43","8.5.45","8.5.46","8.5.47","8.5.49","8.5.5","8.5.50","8.5.51","8.5.53","8.5.54","8.5.55","8.5.56","8.5.57","8.5.58","8.5.59","8.5.6","8.5.8","8.5.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/02/GHSA-vvw4-rfwf-p6hx/GHSA-vvw4-rfwf-p6hx.json"}}],"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-17527"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/21e3408671aac7e0d7e264e720cac8b1b189eb29"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/8d2fe6894d6e258a6d615d7f786acca80e6020cb"},{"type":"WEB","url":"https://github.com/apache/tomcat/commit/d56293f816d6dc9e2b47107f208fa9e95db58c65"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rce5ac9a40173651d540babce59f6f3825f12c6d4e886ba00823b11e5@%3Cannounce.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rce5ac9a40173651d540babce59f6f3825f12c6d4e886ba00823b11e5@%3Cannounce.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rd5babd13d7a350b369b2f647b4dd32ce678af42f9aba5389df1ae6ca@%3Cusers.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2020/12/msg00022.html"},{"type":"WEB","url":"https://security.gentoo.org/glsa/202012-23"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20201210-0003"},{"type":"WEB","url":"https://tomcat.apache.org/security-10.html"},{"type":"WEB","url":"https://tomcat.apache.org/security-8.html"},{"type":"WEB","url":"https://tomcat.apache.org/security-9.html"},{"type":"WEB","url":"https://www.debian.org/security/2021/dsa-4835"},{"type":"WEB","url":"https://www.oracle.com//security-alerts/cpujul2021.html"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpuApr2021.html"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpuapr2022.html"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpujan2022.html"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rce5ac9a40173651d540babce59f6f3825f12c6d4e886ba00823b11e5%40%3Cannounce.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rca833c6d42b7b9ce1563488c0929f29fcc95947d86e5e740258c8937@%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rbba08c4dcef3603e36276d49adda8eedbe458c5104314b4038f697e1@%3Cusers.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rabbe6b3ae6a9795641d7a05c00d2378d5bbbe4240b7e20f09b092cce@%3Cissues.guacamole.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/raa0e9ad388c1e6fd1e301b5e080f9439f64cb4178119a86a4801cc53@%3Cdev.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/ra9fcdb904dd2e2256ef90b3e4ced279cd464cb0ab63a6c64df5c010d@%3Cannounce.tomcat.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/ra9fcdb904dd2e2256ef90b3e4ced279cd464cb0ab63a6c64df5c010d@%3Cannounce.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/ra35c8d617b17d59f40011
