8bc59f87ec Fixed CVE-2019-7635 and bug 4498 - Heap-Buffer Overflow in Blit1to4 pertaining to SDL_blit_1.c 
Petr Pisar

The root cause is that the POC BMP file declares 3 colors used and 4 bpp palette, but pixel at line 28 and column 1 (counted from 0) has color number 3. Then when the image loaded into a surface is passed to SDL_DisplayFormat(), in order to convert it to a video format, a used bliting function looks up a color number 3 in a 3-element long color bliting map. (The map obviously has the same number entries as the surface format has colors.)

Proper fix should refuse broken BMP images that have a pixel with a color index higher than declared number of "used" colors. Possibly more advanced fix could try to relocate the out-of-range color index into a vacant index (if such exists).

c528615626 hidapi: Add support for Wii U/Switch USB GameCube controller adapter. 
Note that a single USB device is responsible for all 4 joysticks, so a large
rewrite of the DeviceDriver functions was necessary to allow a single device to
produce multiple joysticks.

ea4c4cfc28 Fixed bug 4500 - Heap-Buffer Overflow in Map1toN pertaining to SDL_pixels.c 
Petr Pisar

The reproducer has these data in BITMAPINFOHEADER:

biSize = 40
biBitCount = 8
biClrUsed = 131075

SDL_LoadBMP_RW() function passes biBitCount as a color depth to SDL_CreateRGBSurface(), thus 256-color pallete is allocated. But then biClrUsed colors are read from a file and stored into the palette. SDL_LoadBMP_RW should report an error if biClrUsed is greater than 2^biBitCount.
