Hi Armin,

I hope it is ok to upgrade libXtst, please let me know if you want to keep the 
same version and apply the patch instead of upgrade.

 The upgrade have only following changes:

2013-05-31      libXtst 1.2.2libXtst-1.2.2

This does not affect master. According to Mitre this affects libXtst before 
1.2.3:

Multiple integer overflows in X.org libXtst before 1.2.3 allow remote X servers 
to trigger out-of-bounds memory access operations by leveraging the lack of 
range checks.

Cheers
