Lack of PNG format verification
iosifache opened this issue · comments
As the cute_png.h
library is used to load and parse PNG files, the returned image is not verified. This could cause the program's functionality to be disrupted.
An example I encountered was when the PNG headers stored excessive values for the image's height and width (despite the fact that the pixels are not stored in the data section of the format). This causes the malloc
from the function cp_to_rgb
to return NULL
and, as a result of the pointer dereferencing below, the program will generate a SIGSERV
and stop working.
how did you get this software to work.
@tax-evasion6967, just following the README.md
for building the executable on Linux and running it.
