{"id":"ALPINE-CVE-2023-5574","details":"A use-after-free flaw was found in xorg-x11-server-Xvfb. This issue occurs in Xvfb with a very specific and legacy configuration (a multi-screen setup with multiple protocol screens, also known as Zaphod mode). If the pointer is warped from a screen 1 to a screen 0, a use-after-free issue may be triggered during shutdown or reset of the Xvfb server, allowing for possible escalation of privileges or denial of service.","modified":"2026-10-27T08:33:40.791723006Z","published":"2023-10-25T20:15:18.717Z","upstream":["CVE-2023-5574"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2023-5574"}],"affected":[{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.9-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2023-5574.json"}},{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.9-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2023-5574.json"}},{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.9-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2023-5574.json"}},{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.9-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2023-5574.json"}},{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.9-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2023-5574.json"}},{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.9-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2023-5574.json"}},{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.9-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2023-5574.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
