{"id":"ALPINE-CVE-2023-6816","details":"A flaw was found in X.Org server. Both DeviceFocusEvent and the XIQueryPointer reply contain a bit for each logical button currently down. Buttons can be arbitrarily mapped to any value up to 255, but the X.Org Server was only allocating space for the device's particular number of buttons, leading to a heap overflow if a bigger value was used.","modified":"2026-11-03T06:32:03.545513770Z","published":"2024-01-18T05:15:08.607Z","upstream":["CVE-2023-6816"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2023-6816"}],"affected":[{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.11-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-6816.json"}},{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.11-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-6816.json"}},{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.11-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-6816.json"}},{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.11-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-6816.json"}},{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.11-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-6816.json"}},{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.11-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-6816.json"}},{"package":{"name":"xwayland","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/xwayland?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"23.2.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-6816.json"}},{"package":{"name":"xwayland","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/xwayland?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"23.2.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-6816.json"}},{"package":{"name":"xwayland","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/xwayland?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"23.2.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-6816.json"}},{"package":{"name":"xwayland","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/xwayland?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"23.2.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-6816.json"}},{"package":{"name":"xwayland","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/xwayland?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"23.2.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-6816.json"}},{"package":{"name":"xwayland","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/xwayland?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"23.2.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-6816.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
