Please review security patch [CVE-2014-7911]

[Moritz Bandemer]

I've corrected some line numbers of an existing patch to make a correct 
one, which could apply to the Replicant sources.
I've successfully applied the attached patch, recompiled Replicant-and 
after that I have successfully checked, that Replicant isn't vulnerale 
to the "Privilege Escalation vulnerability - CVE-2014-7911" anymore.
Ticket reference (Bug #1113): http://redmine.replicant.us/issues/1113
Please review the patch and apply it, if you like.
