==============================================================

Firmware version:
1.05B64_RU

New Features:
None

Problems Fixed:
1. Security Vulnerabilities Addressed: devices respond clients some unnecessary information, and hence give hackers a chance to hack devices. 
Reference: CVE-2013-5945, CVE-2013-5946
Solution: Remove all unnecessary root user accounts.
2. Security Vulnerabilities Addressed: Persistent root access. Reference: http://packetstormsecurity.com/files/118355/D-Link-DSR-250N-Backdoor.html
Solution: Removed CLI commands that could allow someone to overwrite the super user password and gain root access to the device.
3. Security Vulnerabilities Addressed: UPnP vulnerabilities identified in the audit of libUPnP code base.
Reference: CVE-2012-5958, CVE-2012-5959, CVE-2012-5961, CVE-2012-5962, CVE-2012-5963, CVE-2012-5964, CVE-2012-5965
Solution: Patched Intel SDK libupnp v1.3.1 to add the following; 
1) use 'snprintf' and 'strncpy' instead of 'sprintf' and 'strcpy', 
2) While doing a 'strncpy', check if we are copying more bytes than the destination string size.
4. Devices don't respond ARP requests sent by a utility called ARPING
5. Wrong wordings for URL blocked keyword in the online help.
6. After rebooting devices, synchronization with NTP didn't works.
7. Multiport port forwarding doesn't work as our expecting behavior.
8. Unable to ping VLAN hosts from PPTP clients when VLAN PVID is configured with 2 digits or more.
