Detailsinfo

A vulnerability, which was classified as critical, has been found in SDL 2.0.5. Affected by this issue is an unknown code of the component RGB Surface. The manipulation as part of a Image File leads to a integer overflow vulnerability. Using CWE to declare the problem leads to CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The bug was discovered 10/10/2017. The weakness was shared 10/11/2017 by Yves Younan (Website). The advisory is shared for download at securityfocus.com. This vulnerability is handled as CVE-2017-2888 since 12/01/2016. The attack may be launched remotely. No form of authentication is required for exploitation. Successful exploitation requires user interaction by the victim. There are neither technical details nor an exploit publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 104195 (Fedora 25 : SDL2 (2017-5934ecf841)), which helps to determine the existence of the flaw in a target environment.
