- CVE-2019-7573 (arbitrary code execution)

SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has
a heap-based buffer over-read in InitMS_ADPCM in audio/SDL_wave.c
(inside the wNumCoef loop).

- CVE-2019-7574 (arbitrary code execution)

SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has
a heap-based buffer over-read in IMA_ADPCM_decode in audio/SDL_wave.c.

- CVE-2019-7575 (arbitrary code execution)

SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has
a heap-based buffer overflow in MS_ADPCM_decode in audio/SDL_wave.c.

- CVE-2019-7576 (arbitrary code execution)

SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has
a heap-based buffer over-read in InitMS_ADPCM in audio/SDL_wave.c
(outside the wNumCoef loop).

- CVE-2019-7577 (arbitrary code execution)

SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has
a buffer over-read in SDL_LoadWAV_RW in audio/SDL_wave.c.

- CVE-2019-7578 (arbitrary code execution)

SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has
a heap-based buffer over-read in InitIMA_ADPCM in audio/SDL_wave.c.

- CVE-2019-7635 (arbitrary code execution)

SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has
a heap-based buffer over-read in Blit1to4 in video/SDL_blit_1.c.

- CVE-2019-7636 (arbitrary code execution)

SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has
a heap-based buffer over-read in SDL_GetRGB in video/SDL_pixels.c.

- CVE-2019-7638 (arbitrary code execution)

SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has
a heap-based buffer over-read in Map1toN in video/SDL_pixels.c.

Impact
======

An attacker can execute arbitrary code on the affected host via a
crafted audio or video file.
