However, currently, I do not have permission to access [LeakCheck.cpp](http://www.cse.unsw.edu.au/~corg/svf/doxygen/_leak_checker_8cpp_source.html) and [ProgSlice.cpp](http://www.cse.unsw.edu.au/~corg/svf/doxygen/_prog_slice_8cpp_source.html).

Hi, I further checked the details of libpng's implementation, and found some possible useful information. Specifically, libpng use the function `png_zlib_inflate(png_ptr, 0)` to decode the zlib stream, and some comments...

I conduct a rough analysis and find the root cause lies in the function `mystrtod()`, where the loop executes 1622094001 times, which should be avoided.

also accept invalid strings (i.e., containing unescaped control characters), which is not allowed according to the section 7 of specification. It can be reproduced with the following buf: ``` char...

Thanks for posting here, I am DLiang Fun who sends this email. Here is the png file that witnesses three different implementations (i.e., libpng, lodepng, libspng) handle it differently with...
