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).

47fb781b94 BlitNtoN BlitNtoNKey: remove non-aligned word read/store (bpp 3<->4) (Bug 4503) 
Mips and (old) ARM doesn't allow word read/write when adress isn't 4bytes
aligned. So just remove that.

6fbe9e23fa raspberry: expose second display. 
This lets apps see and choose between both an HDMI and DSI-connected display,
such as a television and the Pi Foundation's official touchscreen. It only
exposes the second display if the hardware reports that it is connected.

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.

afd1b3dae4 Fix invalid memory access and optimise Blit_3or4_to_3or4__* 
Fix invalid write at last pixel of the surface:
  when surface has no padding (pitch == w * bpp) and bpp is 3
  with Blit, no colorkey, and NO_ALPHA same or inverse rgb triplet

Optimise by using int32 access:

670f3d3327 Fixed bug 4484 - use SIMD aligned memory for SDL_Surface 
Surfaces are allocated using SDL_SIMDAlloc()
They are marked with SDL_SIMD_ALIGNED flag to appropriatly free them with SDL_SIMDFree()
(Flag is cleared when pixels is free'd in RLE, in case user would hijack the pixels ptr)

When providing its own memory pointer (SDL_CreateRGBSurfaceFrom()) and clearing
SDL_PREALLOC  to delegate to SDL the memory free, it's the responsability of the user
to add SDL_SIMD_ALIGNED or not, whether the pointer has been allocated with SDL_malloc() or
SDL_SIMDAlloc().

cd25c83aad Fix blit with blending (Blit_A) to RGB332 which has no palette 2019-01-30 17:16:08 +01:00
Sylvain Becker
5b07148f73 Fixed failing SDL_ConvertSurface() when blit has failed. 
Some blit combination are not supported (eg ARGB8888 -> SDL_PIXELFORMAT_INDEX1MSB)
So prevent SDL_ConvertSurface from creating a broken surface, which cannot be blitted

All following conversion are faster (no colorkey, no blending).
(ratio isn't very accurate)

6d89a7bc71 Emscripten: remove GLES_DeleteContext implementation 
It was calling glClear without a context. The issue it was trying to
solve was actually that after destroying a window and creating a new one
, the contents of the old window were preserved. This no longer happens
since we resize the window to nothing on destroy.

e5f8801f55 Android: prevent concurrency in Android_SetScreenResolution() when exiting 
by checking Android_Window validity

- SDLThread: user application is exiting:
    SDL_VideoQuit() and clearing SDL_GetVideoDevice()

- ActivityThread is changing orientation/size
    surfaceChanged() > Android_SetScreenResolution() > SDL_GetVideoDevice()

- Separate function into Android_SetScreenResolution() and Android_SendResize(),
    formating, and mark Android_DeviceWidth/Heigh as static

dc263450ff Android: create Pause/ResumeSem semaphore at higher level than CreateWindow() 
- If you call onPause() before CreateWindow(), SDLThread will run in infinite loop in background.

- If you call onPause() between a DestroyWindow() and a new CreateWindow(), semaphores are invalids.

SDLActivity.java: the first resume() starts the SDLThread, don't call
nativeResume() as it would post ResumeSem. And the first pause would
automatically be resumed.
