发布于3月6日3月6日 超级管理员 Huawei EulerOS: CVE-2024-31081: xorg-x11-server security update Severity 4 CVSS (AV:L/AC:M/Au:N/C:P/I:P/A:P) Published 04/04/2024 Created 07/16/2024 Added 07/16/2024 Modified 12/12/2024 Description A heap-based buffer over-read vulnerability was found in the X.org server's ProcXIPassiveGrabDevice() 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.
