An exploitable code execution vulnerability exists in the PCX image-rendering functionality of SDL2_image 2.0.4. A specially crafted PCX image can cause a heap overflow, resulting in code execution. An attacker can display a specially crafted image to trigger this vulnerability.
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
The product writes data past the end, or before the beginning, of the intended buffer.
