  - SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has a heap-based buffer over-read in
    BlitNtoN in video/SDL_blit_N.c when called from SDL_SoftBlit in video/SDL_blit.c. (CVE-2019-13616)

  - SDL (Simple DirectMedia Layer) 2.x through 2.0.9 has a heap-based buffer over-read in
    Fill_IMA_ADPCM_block, caused by an integer overflow in IMA_ADPCM_decode() in audio/SDL_wave.c.
    (CVE-2019-13626)

  - SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has a buffer over-read in
    IMA_ADPCM_nibble in audio/SDL_wave.c. (CVE-2019-7572)

  - 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-2019-7573)

  - 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-2019-7574)

  - 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-2019-7575)

  - 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-2019-7576)

  - 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-2019-7577)

  - 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-2019-7578)

  - 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-2019-7635)

  - 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-2019-7636)

  - 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. (CVE-2019-7638)

  - SDL (Simple DirectMedia Layer) through 2.0.12 has an Integer Overflow (and resultant SDL_memcpy heap
    corruption) in SDL_BlitCopy in video/SDL_blit_copy.c via a crafted .BMP file. (CVE-2020-14409)

  - SDL (Simple DirectMedia Layer) through 2.0.12 has a heap-based buffer over-read in
    Blit_3or4_to_3or4__inversed_rgb in video/SDL_blit_N.c via a crafted .BMP file. (CVE-2020-14410)

  - There is a heap overflow problem in video/SDL_pixels.c in SDL (Simple DirectMedia Layer) 2.x to 2.0.18
    versions. By crafting a malicious .BMP file, an attacker can cause the application using this library to
    crash, denial of service or Code execution. (CVE-2021-33657)

  - A potential memory leak issue was discovered in SDL2 in GLES_CreateTexture() function in
    SDL_render_gles.c. The vulnerability allows an attacker to cause a denial of service attack. The
    vulnerability affects SDL2 v2.0.4 and above. SDL-1.x are not affected. (CVE-2022-4743)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
