Vulnerability details
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
An exploitable code execution vulnerability exists in the XPM image rendering function of SDL2_image 2.0.4. A specially crafted XPM image can cause an integer overflow in the colorhash function, allocating too small of a buffer. This buffer can then be written out of bounds, resulting in a heap overflow, ultimately ending in code execution. An attacker can display a specially crafted image to trigger this vulnerability.
