Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/sdl-1.2.15-i586-13_slack15.0.txz: Rebuilt.
 This update fixes a heap overflow problem in video/SDL_pixels.c in SDL.
 By crafting a malicious .BMP file, an attacker can cause the application
 using this library to crash, denial of service, or code execution.
 Thanks to marav for the heads-up.

 (* Security fix *)
