RE: Windows Command Processor CMD.EXE Buffer Overflow

Mmmm i'm not sure in my OS Win XP SP2 Spanish, it crashes

EventType : BEX     P1 : cmd.exe     P2 : 5.1.2600.2180     P3 : 41107ebe

P4 : unknown     P5 : 0.0.0.0     P6 : 00000000     P7 : 00410041     
P8 : c0000005     P9 : 00000008  


Maybe it depends on lenguaje version.
