An exploitable heap-based buffer overflow vulnerability exists when loading a PCX file in SDL2image, version 2.0.4. A missing error handler can lead to a buffer overflow and potential code execution. An attacker can provide a specially crafted image file to trigger this vulnerability.

An exploitable integer overflow vulnerability exists when loading a PCX file in SDL2image 2.0.4. A specially crafted file can cause an integer overflow, resulting in too little memory being allocated, which can lead to a buffer overflow and potential code execution. An attacker can provide a specially crafted image file to trigger this vulnerability.
