{"id":"CVE-2024-31083","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":"2026-04-16T04:37:20.785586014Z","published":"2024-04-05T12:15:37Z","related":["ALSA-2024:2037","ALSA-2024:2616","ALSA-2024:3258","ALSA-2024:3261","ALSA-2024:3343","ALSA-2024:9093","ALSA-2024:9122","CGA-cfg4-2gc2-9pgm","RLSA-2024:2616","SUSE-SU-2024:1199-1","SUSE-SU-2024:1260-1","SUSE-SU-2024:1261-1","SUSE-SU-2024:1262-1","SUSE-SU-2024:1263-1","SUSE-SU-2024:1264-1","SUSE-SU-2024:1265-1","SUSE-SU-2024:2776-1","openSUSE-SU-2024:13828-1","openSUSE-SU-2024:13829-1"],"references":[{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:1785"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:2036"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:2037"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:2038"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:2039"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:2040"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:2041"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:2042"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:2080"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:2616"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:3258"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:3261"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:3343"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:9093"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2024:9122"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2025:12751"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2272000"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2024-31083"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2024/04/03/13"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2024/04/12/10"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/04/msg00009.html"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/6TF7FZXOKHIKPZXYIMSQXKVH7WITKV3V/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/EBLQJIAXEDMEGRGZMSH7CWUJHSVKUWLV/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/P73U4DAAWLFZAPD75GLXTGMSTTQWW5AP/"}],"schema_version":"1.7.5"}
