{"id":"ALPINE-CVE-2024-31082","details":"A heap-based buffer over-read vulnerability was found in the X.org server's ProcAppleDRICreatePixmap() function. This issue occurs when byte-swapped length values are used in replies, potentially leading to memory leakage and segmentation faults, particularly when triggered by a client with a different endianness. This vulnerability could be exploited by an attacker to cause the X server to read heap memory values and then transmit them back to the client until encountering an unmapped page, resulting in a crash. Despite the attacker's inability to control the specific memory copied into the replies, the small length values typically stored in a 32-bit integer can result in significant attempted out-of-bounds reads.","modified":"2026-11-03T06:32:49.584504253Z","published":"2024-04-04T14:15:10.833Z","upstream":["CVE-2024-31082"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2024-31082"}],"affected":[{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.12-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-31082.json"}},{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.12-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-31082.json"}},{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.12-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-31082.json"}},{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.12-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-31082.json"}},{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.12-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-31082.json"}},{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.12-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2024-31082.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:H"}]}
