Overview

Affected versions of this package are vulnerable to Out-of-bounds Read due to the stbi__gif_load_next function. An attacker can leak internal memory allocation information by triggering an out of bounds memcpy read with a crafted image file. This happens because two_back points to a memory address lower than the start of the buffer out.
