Oh………………………… Big mistake. I might advertised too soon.

I saw changes were pushed in master, so I thought the next version 
(which was 2.7.1) would be the one which will include the fix.

But as pointed out on 
https://security-tracker.debian.org/tracker/CVE-2016-2324 no versions 
including the fixes were released yet, and even 2.7.3 still include 
path_name(). I didn’t checked the code (Sorrrry).

So the only way to fix it is to draw your compilers and compile the 
current master branch at https://git.kernel.org/cgit/git/git.git/.

Or do like github did by using the patches at 
http://thread.gmane.org/gmane.comp.version-control.git/286253 and 
http://thread.gmane.org/gmane.comp.version-control.git/286008

I’m really sorry…
