Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 33 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2021-9d65b22041 advisory.

- 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)

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

Solution

Update the affected mingw-SDL2 package.
