CVE-2017-2888
Published: 11 October 2017
An exploitable integer overflow vulnerability exists when creating a new RGB Surface in SDL 2.0.5. 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.
From the Ubuntu Security Team
