Description Peter Hutterer 2014-02-04 21:38:59 UTC

Description of problem:
XSetDeviceButtonMapping takes a user-specified map of button mappings (with a user-specified length). The server checks if each button is down before applying a mapping but it erroneously treats each button number as an array index instead of a bitflag, causing out-of-bounds access on the fixed-size array.
