This issue occurs when AllocateGlyph() is called to store new glyphs sent by the client to the X server, potentially resulting in multiple entries pointing to the same non-refcounted glyphs. Consequently, ProcRenderAddGlyphs() may free a glyph, leading to a use-after-free scenario when the same glyph pointer is subsequently accessed. This flaw allows an authenticated attacker to execute arbitrary code on the system by sending a specially crafted request.","title":"CVE description"}],"product_status":{"recommended":["SUSE Linux Enterprise Workstation Extension 15 SP5:xwayland-22.1.5-150500.7.22.1.x86_64","openSUSE Leap 15.5:xwayland-22.1.5-150500.7.22.1.aarch64","openSUSE Leap 15.5:xwayland-22.1.5-150500.7.22.1.ppc64le","openSUSE Leap 15.5:xwayland-22.1.5-150500.7.22.1.s390x","openSUSE Leap 15.5:xwayland-22.1.5-150500.7.22.1.x86_64","openSUSE Leap 15.5:xwayland-devel-22.1.5-150500.7.22.1.aarch64","openSUSE Leap 15.5:xwayland-devel-22.1.5-150500.7.22.1.ppc64le","openSUSE Leap 15.5:xwayland-devel-22.1.5-150500.7.22.1.s390x","openSUSE Leap 15.5:xwayland-devel-22.1.5-150500.7.22.1.x86_64"]},"references":[{"category":"external","summary":"CVE-2024-31083","url":"https://www.suse.com/security/cve/CVE-2024-31083"},{"category":"external","summary":"SUSE Bug 1222312 for CVE-2024-31083","url":"https://bugzilla.suse.com/1222312"}],"remediations":[{"category":"vendor_fix","details":"To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or \"zypper patch\".\n","product_ids":["SUSE Linux Enterprise Workstation Extension 15 SP5:xwayland-22.1.5-150500.7.22.1.x86_64","openSUSE Leap 15.5:xwayland-22.1.5-150500.7.22.1.aarch64","openSUSE Leap 15.5:xwayland-22.1.5-150500.7.22.1.ppc64le","openSUSE Leap 15.5:xwayland-22.1.5-150500.7.22.1.s390x","openSUSE Leap 15.5:xwayland-22.1.5-150500.7.22.1.x86_64","openSUSE Leap 15.5:xwayland-devel-22.1.5-150500.7.22.1.aarch64","openSUSE Leap 15.5:xwayland-devel-22.1.5-150500.7.22.1.ppc64le","openSUSE Leap 15.5:xwayland-devel-22.1.5-150500.7.22.1.s390x","openSUSE Leap 15.5:xwayland-devel-22.1.5-150500.7.22.1.x86_64"]}],"scores":[{"cvss_v3":{"baseScore":7.8,"baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"products":["SUSE Linux Enterprise Workstation Extension 15 SP5:xwayland-22.1.5-150500.7.22.1.x86_64","openSUSE Leap 15.5:xwayland-22.1.5-150500.7.22.1.aarch64","openSUSE Leap 15.5:xwayland-22.1.5-150500.7.22.1.ppc64le","openSUSE Leap 15.5:xwayland-22.1.5-150500.7.22.1.s390x","openSUSE Leap 15.5:xwayland-22.1.5-150500.7.22.1.x86_64","openSUSE Leap 15.5:xwayland-devel-22.1.5-150500.7.22.1.aarch64","openSUSE Leap 15.5:xwayland-devel-22.1.5-150500.7.22.1.ppc64le","openSUSE Leap 15.5:xwayland-devel-22.1.5-150500.7.22.1.s390x","openSUSE Leap 15.5:xwayland-devel-22.1.5-150500.7.22.1.x86_64"]}],"threats":[{"category":"impact","date":"2024-04-12T13:06:00Z","details":"important"}],"title":"CVE-2024-31083"}]}
