{"id":"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":"2026-03-15T22:48:56.154270Z","published":"2023-10-25T20:15:18.717Z","related":["ALSA-2024:2298","MGASA-2023-0307","SUSE-SU-2023:4269-1","SUSE-SU-2023:4272-1","SUSE-SU-2023:4292-1","SUSE-SU-2023:4293-1","SUSE-SU-2023:4306-1","SUSE-SU-2023:4338-1","openSUSE-SU-2024:13361-1","openSUSE-SU-2024:13467-1"],"references":[{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:2298"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2023-5574"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20231130-0004/"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2244735"},{"type":"FIX","url":"https://lists.x.org/archives/xorg-announce/2023-October/003430.html"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"1.13.0"}]},{"events":[{"introduced":"0"},{"last_affected":"7.0"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-5574.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
