{"id":"ALPINE-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":"2026-09-10T06:17:54.425940072Z","published":"2019-06-11T22:29:04.170Z","upstream":["CVE-2019-0197"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2019-0197"}],"affected":[{"package":{"name":"apache2","ecosystem":"Alpine:v3.10","purl":"pkg:apk/alpine/apache2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.39-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-0197.json"}},{"package":{"name":"apache2","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/apache2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.39-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-0197.json"}},{"package":{"name":"apache2","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/apache2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.39-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-0197.json"}},{"package":{"name":"apache2","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/apache2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.39-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-0197.json"}},{"package":{"name":"apache2","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/apache2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.39-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-0197.json"}},{"package":{"name":"apache2","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/apache2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.39-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-0197.json"}},{"package":{"name":"apache2","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/apache2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.39-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-0197.json"}},{"package":{"name":"apache2","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/apache2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.39-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-0197.json"}},{"package":{"name":"apache2","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/apache2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.39-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-0197.json"}},{"package":{"name":"apache2","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/apache2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.39-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-0197.json"}},{"package":{"name":"apache2","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/apache2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.39-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-0197.json"}},{"package":{"name":"apache2","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/apache2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.39-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-0197.json"}},{"package":{"name":"apache2","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/apache2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.39-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-0197.json"}},{"package":{"name":"apache2","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/apache2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.39-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-0197.json"}},{"package":{"name":"apache2","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/apache2?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.39-r0"}]}],"ecosystem_specific":{},
