2) Bug
|
|
======
|
|
|
|
|
|
Through the S0 files it's possible to exploit various array overflow
|
|
vulnerabilities for writing the word 0xfffd in an arbitrary zone of the
|
|
memory.
|
|
The following is one of these bugs, from VCF132.dll:
|
|
|
|
1D044E91 |. 0FB750 06 ||MOVZX EDX,WORD PTR DS:[EAX+6] ; EDX controlled
|
|
1D044E95 |. 8B0491 ||MOV EAX,DWORD PTR DS:[ECX+EDX*4]
|
|
1D044E98 |. 8BCB ||MOV ECX,EBX
|
|
1D044E9A |. 66:C740 04 FDFF ||MOV WORD PTR DS:[EAX+4],0FFFD ; write2
|
|
|
|
For the other array overflows it's enough to search the 0xfffd constant
|
|
and all the operations like the above one.
