Fr3DBr | Hello, im trying to initialize my module using the example on skulls website. Altough i noticed that its usually crashing inside the module when we call init at : [code] CPU Disasm Address Hex dump Command Comments 005053DD 56 PUSH ESI <--- ESI Had the address to the Function Callback Struct PTR 005053DE BE 0CA00000 MOV ESI,0A00C 005053E3 EB 08 JMP SHORT 005053ED 005053E5 6A 00 PUSH 0 005053E7 FF15 04900000 CALL DWORD PTR DS:[9004] 005053ED 33C0 XOR EAX,EAX 005053EF 40 INC EAX 005053F0 8BD6 MOV EDX,ESI 005053F2 33C9 XOR ECX,ECX 005053F4 F0:0FB10A LOCK CMPXCHG DWORD PTR DS:[EDX],ECX <------ crash here 005053F8 85C0 TEST EAX,EAX 005053FA ^ 74 E9 JE SHORT 005053E5 005053FC 5E POP ESI 005053FD C3 RETN [/code] EDX points to the following : 000A00C and ECX is 000000. So im wondering, whats its exactly the module trying to do here ? seems it replaces the reference to the function callback array, and changes it to A00C but wtf lol ? :D | January 24, 2010, 5:06 PM |
Fr3DBr | Ok this was a issue with the global variables that didnt got properly replaced in the module, so as we can see we had a 'kaboom' there :P | January 24, 2010, 5:41 PM |
