The version of tested product installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1500 advisory.

  • 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 overflow in SDL_FillRect in video/SDL_surface.c. (CVE-2019-7637)

  • 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)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
