Fixed In Version: xorg-server-21.1.11, xwayland-23.2.4
Doc Type: ---
Doc Text:
A flaw was found in X.Org server. Both DeviceFocusEvent and the XIQueryPointer reply contain a bit for each logical button currently down. Buttons can be arbitrarily mapped to any value up to 255, but the X.Org Server was only allocating space for the device's particular number of buttons, leading to a heap overflow if a bigger value was used.

Description Patrick Del Bello 2024-01-10 14:02:10 UTC 
Both DeviceFocusEvent and the XIQueryPointer reply contain a bit for each logical button currently down. Buttons can be arbitrarily mapped to
any value up to 255 but the X.Org Server was only allocating space for the device's number of buttons, leading to a heap overflow if a bigger value
was used.
