This update for SDL2 fixes the following issues:

- CVE-2017-2888: An exploitable integer overflow vulnerability exists
  when creating a new RGB Surface in SDL. 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. (bsc#1062784)
