Hello all, I've been inundated with e-mails asking whether operating systems other than Windows are affected by XFDF overflow. Whilst I did not state that Windows is the only OS affected, and I should have done, I thought it was clear, incorrectly, that Adobe Acrobat Reader for Windows was indeed the only one and not Mac, *nix, etc.
>From the original advisory: When the xfdf file is parsed an unsafe call to sprintf is made in preparation for outputting a debug message using OutputDebugString. OutputDebugString is a Win32 API function, exported by kernel32.dll. Conseqently, the vulnerable code path will exist only in the Windows version of Adobe Acrobat Reader. I hope this clears up any confusion.
