X.Org Server Vulnerability Could Lead to Application Crash, Privilege Escalation, or Remote Code Execution

CVE-2024-0229

Summary

The vulnerability arises from an out-of-bounds memory access flaw present in the X.Org server, a software that handles graphical displays in Unix-like operating systems. This flaw is triggered when a device that has been 'frozen' by a sync grab is subsequently reattached to a new master device, creating a condition where improper memory access can occur. Exploitation of this vulnerability may lead to application crashes, and in scenarios where the server operates with elevated privileges, it could enable local privilege escalation. Additionally, in environments that utilize SSH X11 forwarding, this defect poses a risk of remote code execution, presenting significant security challenges for users relying on this system.
