{"id":"MGASA-2021-0357","summary":"Updated tomcat packages fix security vulnerabilities","details":"When responding to new h2c connection requests, Apache Tomcat versions \n9.0.0.M1 to 9.0.41 could duplicate request headers and a limited amount of\nrequest body from one request to another meaning user A and user B could both\nsee the results of user A's request (CVE-2021-25122).\n\nThe fix for CVE-2020-9484 was incomplete. When using Apache Tomcat 9.0.0.M1 to\n9.0.41 with a configuration edge case that was highly unlikely to be used, the\nTomcat instance was still vulnerable to CVE-2020-9494 (CVE-2021-25329).\n","modified":"2026-04-16T04:42:28.014310143Z","published":"2021-07-20T10:46:47Z","upstream":["CVE-2021-25122","CVE-2021-25329"],"references":[{"type":"ADVISORY","url":"https://advisories.mageia.org/MGASA-2021-0357.html"},{"type":"REPORT","url":"https://bugs.mageia.org/show_bug.cgi?id=28501"},{"type":"WEB","url":"https://www.openwall.com/lists/oss-security/2021/03/01/1"},{"type":"WEB","url":"https://www.openwall.com/lists/oss-security/2021/03/01/2"},{"type":"WEB","url":"http://tomcat.apache.org/security-9.html#Fixed_in_Apache_Tomcat_9.0.43"},{"type":"WEB","url":"https://lists.opensuse.org/archives/list/security-announce@lists.opensuse.org/thread/YM4ON24PW3U3JLLUNZBOOTDHDHK3EYVO/"},{"type":"WEB","url":"https://www.debian.org/security/2021/dsa-4891"}],"affected":[{"package":{"name":"tomcat","ecosystem":"Mageia:8","purl":"pkg:rpm/mageia/tomcat?arch=source&distro=mageia-8"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"9.0.41-1.2.mga8"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2021-0357.json"}}],"schema_version":"1.7.5","credits":[{"name":"Mageia","contact":["https://wiki.mageia.org/en/Packages_Security_Team"],"type":"COORDINATOR"}]}
