Description Peter Hutterer 2014-02-05 03:13:48 UTC

+++ This bug was initially created as a clone of Bug #1061466 +++

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.

Version-Release number of selected component (if applicable):
xorg-x11-server-Xorg-1.14.4-5.fc20.x86_64
