Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

An exploitable code execution vulnerability exists in the XPM image rendering functionality of SDL2_image 2.0.4. A specially crafted XPM image can cause an integer overflow, 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.

Mitigation
Install update from vendor's website.
