Technical details
The XQueryDeviceState() function in libXi fails to properly validate buffer boundaries when processing ValuatorClass data from the X server, allowing an out-of-bounds read. An attacker with access to a compromised or malicious X server can trigger this by sending a crafted XQueryDeviceState reply with insufficient data. The fix adds proper bounds checking before reading valuator data from the server response.
