python: Fix CVE-2014-1912
A remote user can send specially crafted data to trigger a buffer overflow
in socket.recvfrom_into() and execute arbitrary code on the target system.
The code will run with the privileges of the target service.
This back-ported patch fixes CVE-2014-1912
(From OE-Core rev: 344049ccfa59ae489c35fe0fb7592f7d34720b51)
