Overview

Affected versions of this package are vulnerable to Improper Restriction of Operations within the Bounds of a Memory Buffer due to improper allocation of space for device buttons in DeviceFocusEvent and ProcXIQueryPointer. An attacker can achieve arbitrary code execution or cause a denial of service by sending crafted input that maps buttons to a value higher than the allocated space, leading to a heap overflow.
