Update description for CVE-2014-4114

This updates the description for ms14_060_sandworm.

@jvazquez-r7 I think the commits are caused by me updating to the latest upstream master when I started my branch, and you probably haven't updated in a while?? I guess you can cherry-pick 4c0048f26a40dbf33cac5763a1b6703597fb17ea?
