If that PNG of yours is not just an example note that you can detect easily if the PNG as any extra data (which may or may not indicate an attempt as mischief) and reject the (rare) PNGs with extra data. I ran a script checking the thousands of PNGs on my system and found three with extra data, all three probably due to the "PNG acropalypse" bug (but mischief cannot be ruled out). P.S: btw I'm not implying using extra data that shouldn't be there in a PNG is the only way to have a malicious PNG. |
