The Ubuntu security team deemed this advisory irrelevant for Ubuntu:14.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libx11 package and not the libx11 package as distributed by Ubuntu.
Multiple off-by-one errors in the (1) MakeBigReq and (2) SetReqLen macros in include/X11/Xlibint.h in X11R6.x and libX11 before 1.6.0 allow remote attackers to have unspecified impact via a crafted request, which triggers a buffer overflow.
