{"id":"AZL-6909","summary":"CVE-2020-17527 affecting package tomcat 9.0.39-5","details":"While investigating bug 64830 it was discovered that Apache Tomcat 10.0.0-M1 to 10.0.0-M9, 9.0.0-M1 to 9.0.39 and 8.5.0 to 8.5.59 could re-use an HTTP request header value from the previous stream received on an HTTP/2 connection for the request associated with the subsequent stream. 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.","modified":"2026-04-01T05:21:32.432665Z","published":"2020-12-03T19:15:12Z","upstream":["CVE-2020-17527"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-17527"}],"affected":[{"package":{"name":"tomcat","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/tomcat"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"9.0.39-5"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-6909.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
