{"id":"CLSA-2026-1785497476","summary":"tomcat: Fix of 5 CVEs","details":"- CVE-2026-55955: add replay protection to the cluster EncryptInterceptor by\n  encrypting a trusted timestamp with each message and rejecting duplicate,\n  stale or future messages via the new replayWindowTime and\n  replayWindowMessageCount attributes (upstream tomcat 9.0.119). The default\n  encryptionAlgorithm also changes from AES/CBC/PKCS5Padding to\n  AES/GCM/NoPadding, because the replay protection is only effective for\n  non-malleable algorithms. NOTE: this changes the encrypted cluster message\n  format, so a cluster using EncryptInterceptor must be restarted as a whole,\n  not node by node","modified":"2026-10-26T09:31:22.232391166Z","published":"2026-07-31T11:31:29Z","upstream":["CVE-2026-55955"],"references":[{"type":"ADVISORY","url":"https://errata.tuxcare.com/els_os/tuxcare9.6esu/CLSA-2026-1785497476.html"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-24880"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25854"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34483"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53404"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55955"}],"affected":[{"package":{"name":"tomcat","ecosystem":"TuxCare:AlmaLinux:9.6","purl":"pkg:rpm/tuxcare/tomcat?distro=almalinux-9.6"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:9.0.87-3.el9_6.3.tuxcare.els12"}]}],"database_specific":{"source":"https://github.com/cloudlinux/tuxcare-osv/tree/main/data/els_os/almalinux9.6esu/CLSA-2026-1785497476.json"}},{"package":{"name":"tomcat-admin-webapps","ecosystem":"TuxCare:AlmaLinux:9.6","purl":"pkg:rpm/tuxcare/tomcat-admin-webapps?distro=almalinux-9.6"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:9.0.87-3.el9_6.3.tuxcare.els12"}]}],"database_specific":{"source":"https://github.com/cloudlinux/tuxcare-osv/tree/main/data/els_os/almalinux9.6esu/CLSA-2026-1785497476.json"}},{"package":{"name":"tomcat-docs-webapp","ecosystem":"TuxCare:AlmaLinux:9.6","purl":"pkg:rpm/tuxcare/tomcat-docs-webapp?distro=almalinux-9.6"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:9.0.87-3.el9_6.3.tuxcare.els12"}]}],"database_specific":{"source":"https://github.com/cloudlinux/tuxcare-osv/tree/main/data/els_os/almalinux9.6esu/CLSA-2026-1785497476.json"}},{"package":{"name":"tomcat-el-3.0-api","ecosystem":"TuxCare:AlmaLinux:9.6","purl":"pkg:rpm/tuxcare/tomcat-el-3.0-api?distro=almalinux-9.6"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:9.0.87-3.el9_6.3.tuxcare.els12"}]}],"database_specific":{"source":"https://github.com/cloudlinux/tuxcare-osv/tree/main/data/els_os/almalinux9.6esu/CLSA-2026-1785497476.json"}},{"package":{"name":"tomcat-jsp-2.3-api","ecosystem":"TuxCare:AlmaLinux:9.6","purl":"pkg:rpm/tuxcare/tomcat-jsp-2.3-api?distro=almalinux-9.6"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:9.0.87-3.el9_6.3.tuxcare.els12"}]}],"database_specific":{"source":"https://github.com/cloudlinux/tuxcare-osv/tree/main/data/els_os/almalinux9.6esu/CLSA-2026-1785497476.json"}},{"package":{"name":"tomcat-lib","ecosystem":"TuxCare:AlmaLinux:9.6","purl":"pkg:rpm/tuxcare/tomcat-lib?distro=almalinux-9.6"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:9.0.87-3.el9_6.3.tuxcare.els12"}]}],"database_specific":{"source":"https://github.com/cloudlinux/tuxcare-osv/tree/main/data/els_os/almalinux9.6esu/CLSA-2026-1785497476.json"}},{"package":{"name":"tomcat-servlet-4.0-api","ecosystem":"TuxCare:AlmaLinux:9.6","purl":"pkg:rpm/tuxcare/tomcat-servlet-4.0-api?distro=almalinux-9.6"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:9.0.87-3.el9_6.3.tuxcare.els12"}]}],"database_specific":{"source":"https://github.com/cloudlinux/tuxcare-osv/tree/main/data/els_os/almalinux9.6esu/CLSA-2026-1785497476.json"}},{"package":{"name":"tomcat-webapps","ecosystem":"TuxCare:AlmaLinux:9.6","purl":"pkg:rpm/tuxcare/tomcat-webapps?distro=almalinux-9.6"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:9.0.87-3.el9_6.3.tuxcare.els12"}]}],"database_specific":{"source":"https://github.com/cloudlinux/tuxcare-osv/tree/main/data/els_os/almalinux9.6esu/CLSA-2026-1785497476.json"}}],"schema_version":"1.9.0"}
