{"id":"AZL-39112","summary":"CVE-2024-31082 affecting package xorg-x11-server for versions less than 1.20.10-11","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":"2026-04-01T05:13:23.427439Z","published":"2024-04-04T14:15:10Z","upstream":["CVE-2024-31082"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-31082"}],"affected":[{"package":{"name":"xorg-x11-server","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/xorg-x11-server"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.20.10-11"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-39112.json"}}],"schema_version":"1.7.5"}
