{"id":"AZL-44382","summary":"CVE-2024-31083 affecting package xorg-x11-server 1.20.10-6","details":"A use-after-free vulnerability was found in the ProcRenderAddGlyphs() function of Xorg servers. 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.","modified":"2026-04-01T05:15:35.461344Z","published":"2024-04-05T12:15:37Z","upstream":["CVE-2024-31083"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-31083"}],"affected":[{"package":{"name":"xorg-x11-server","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/xorg-x11-server"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"1.20.10-6"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-44382.json"}}],"schema_version":"1.7.5"}
