Description Laura Pardo 2018-04-16 20:32:59 UTC

A flaw was found in SDL2_image-2.0.2. An exploitable code execution vulnerability exists in the XCF image rendering functionality of Simple DirectMedia Layer. A specially crafted XCF image can cause an out-of-bounds write on the heap, resulting in code execution. An attacker can display a specially crafted image to trigger this vulnerability.
