High
| Vector | AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
SDL (Simple DirectMedia Layer) versions 2.0.12 and earlier
Description
The issue is related to an integer overflow in the SDL BlitCopy function in the video/SDL blit copy.c component of the Simple DirectMedia Layer library. This can lead to SDL memcpy heap corruption when processing a crafted .BMP file. Exploitation of this issue may allow a remote attacker to access confidential data, compromise its integrity, and cause a denial of service.
Recommendations
For SDL (Simple DirectMedia Layer) versions 2.0.12 and earlier, consider updating to a version later than 2.0.12 to resolve the issue. As a temporary workaround, consider restricting the use of the SDL BlitCopy function in the video/SDL blit copy.c component until a patch is available. Avoid using crafted .BMP files to minimize the risk of exploitation.
