{"id":"CVE-2019-0197","details":"A vulnerability was found in Apache HTTP Server 2.4.34 to 2.4.38. When HTTP/2 was enabled for a http: host or H2Upgrade was enabled for h2 on a https: host, an Upgrade request from http/1.1 to http/2 that was not the first request on a connection could lead to a misconfiguration and crash. Server that never enabled the h2 protocol or that only enabled it for https: and did not set \"H2Upgrade on\" are unaffected by this issue.","modified":"2026-05-18T05:51:47.958987380Z","published":"2019-06-11T22:29:04.170Z","related":["ALSA-2020:4751","SUSE-SU-2019:0873-1","SUSE-SU-2019:0878-1","openSUSE-SU-2019:1209-1"],"database_specific":{"unresolved_ranges":[{"cpes":["cpe:2.3:o:canonical:ubuntu_linux:16.04:*:*:*:esm:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:18.04:*:*:*:lts:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:19.04:*:*:*:*:*:*:*"],"extracted_events":[{"last_affected":"16.04"},{"last_affected":"18.04"},{"last_affected":"19.04"}],"source":"CPE_FIELD","vendor_product":"canonical:ubuntu_linux"},{"cpes":["cpe:2.3:o:fedoraproject:fedora:30:*:*:*:*:*:*:*"],"extracted_events":[{"last_affected":"30"}],"source":"CPE_FIELD","vendor_product":"fedoraproject:fedora"},{"vendor_product":"opensuse:leap","extracted_events":[{"last_affected":"15.0"},{"last_affected":"42.3"}],"source":"CPE_FIELD","cpes":["cpe:2.3:o:opensuse:leap:15.0:*:*:*:*:*:*:*","cpe:2.3:o:opensuse:leap:42.3:*:*:*:*:*:*:*"]},{"cpes":["cpe:2.3:a:oracle:communications_session_report_manager:8.0.0:*:*:*:*:*:*:*","cpe:2.3:a:oracle:communications_session_report_manager:8.1.0:*:*:*:*:*:*:*","cpe:2.3:a:oracle:communications_session_report_manager:8.1.1:*:*:*:*:*:*:*","cpe:2.3:a:oracle:communications_session_report_manager:8.2.0:*:*:*:*:*:*:*"],"extracted_events":[{"last_affected":"8.0.0"},{"last_affected":"8.1.0"},{"last_affected":"8.1.1"},{"last_affected":"8.2.0"}],"source":"CPE_FIELD","vendor_product":"oracle:communications_session_report_manager"},{"vendor_product":"oracle:communications_session_route_manager","extracted_events":[{"last_affected":"8.0.0"},{"last_affected":"8.1.0"},{"last_affected":"8.1.1"},{"last_affected":"8.2.0"}],"source":"CPE_FIELD","cpes":["cpe:2.3:a:oracle:communications_session_route_manager:8.0.0:*:*:*:*:*:*:*","cpe:2.3:a:oracle:communications_session_route_manager:8.1.0:*:*:*:*:*:*:*","cpe:2.3:a:oracle:communications_session_route_manager:8.1.1:*:*:*:*:*:*:*","cpe:2.3:a:oracle:communications_session_route_manager:8.2.0:*:*:*:*:*:*:*"]},{"cpes":["cpe:2.3:a:oracle:enterprise_manager_ops_center:12.3.3:*:*:*:*:*:*:*","cpe:2.3:a:oracle:enterprise_manager_ops_center:12.4.0:*:*:*:*:*:*:*"],"extracted_events":[{"last_affected":"12.3.3"},{"last_affected":"12.4.0"}],"source":"CPE_FIELD","vendor_product":"oracle:enterprise_manager_ops_center"},{"cpes":["cpe:2.3:a:oracle:http_server:12.2.1.3.0:*:*:*:*:*:*:*"],"extracted_events":[{"last_affected":"12.2.1.3.0"}],"source":"CPE_FIELD","vendor_product":"oracle:http_server"},{"vendor_product":"oracle:instantis_enterprisetrack","extracted_events":[{"last_affected":"17.1"},{"last_affected":"17.2"},{"last_affected":"17.3"}],"source":"CPE_FIELD","cpes":["cpe:2.3:a:oracle:instantis_enterprisetrack:17.1:*:*:*:*:*:*:*","cpe:2.3:a:oracle:instantis_enterprisetrack:17.2:*:*:*:*:*:*:*","cpe:2.3:a:oracle:instantis_enterprisetrack:17.3:*:*:*:*:*:*:*"]},{"cpes":["cpe:2.3:a:oracle:retail_xstore_point_of_service:7.0:*:*:*:*:*:*:*","cpe:2.3:a:oracle:retail_xstore_point_of_service:7.1:*:*:*:*:*:*:*"],"extracted_events":[{"last_affected":"7.0"},{"last_affected":"7.1"}],"source":"CPE_FIELD","vendor_product":"oracle:retail_xstore_point_of_service"},{"vendor_product":"redhat:jboss_core_services","extracted_events":[{"last_affected":"1.0"}],"source":"CPE_FIELD","cpes":["cpe:2.3:a:redhat:jboss_core_services:1.0:*:*:*:*:*:*:*"]}]},"references":[{"type":"WEB","url":"https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/84a3714f0878781f6ed84473d1a503d2cc382277e100450209231830%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/e0b8f6e858b1c8ec2ce8e291a2c543d438915037c7af661ab6d33808%40%3Cdev.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r03ee478b3dda3e381fd6189366fa7af97c980d2f602846eef935277d%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r06f0d87ebb6d59ed8379633f36f72f5b1f79cadfda72ede0830b42cf%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r76142b8c5119df2178be7c2dba88fde552eedeec37ea993dfce68d1d%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r9f93cf6dde308d42a9c807784e8102600d0397f5f834890708bf6920%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rc998b18880df98bafaade071346690c2bc1444adaa1a1ea464b93f0a%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rd18c3c43602e66f9cdcf09f1de233804975b9572b0456cc582390b6f%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rd2fb621142e7fa187cfe12d7137bf66e7234abcbbcd800074c84a538%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/re3d27b6250aa8548b8845d314bb8a350b3df326cacbbfdfe4d455234%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"htt
