-Subject: [PATCH] CVE-2019-7638, CVE-2019-7636: Refuse loading BMP images with
- too high number of colors
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-If a BMP file that defines more colors than can fit into
-a palette of color depth defined in the same BMP file is loaded by
-SDL_LoadBMP_RW() function, invalid number of colors is set into
-resulting SDL surface.
-
-Then if the SDL surface is passed to SDL_DisplayFormat() function to
-convert the surface format into a native video format, a buffer
-overread will happen in Map1to1() or Map1toN() function
-(CVE-2019-7638). (The choice of the mapping function depends on
-a actual video hardware.)
-
-In addition SDL_GetRGB() called indirectly from SDL_DisplayFormat()
-performs the same buffer overread (CVE-2019-7636).
-
-There is also probably a buffer overwrite when the SDL_LoadBMP_RW()
-loads colors from a file.
-
-This patch fixes it by refusing loading such badly damaged BMP files.
