Multiple integer overflows in CamlImages 2.2 and earlier might allow context-dependent attackers to execute arbitrary code via a crafted PNG image with large width and height values that trigger a heap-based buffer overflow in the (1) read_png_file or (2) read_png_file_as_rgb24 function.
Weaknesses in this category are related to improper calculation or conversion of numbers.
