Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) Integer overflow (CVE-ID: CVE-2020-14409)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer overflow in the "SDL_BlitCopy" in "video/SDL_blit_copy.c". A remote attacker can use a specially crafted .BMP file, trigger integer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Out-of-bounds read (CVE-ID: CVE-2020-14410)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

A remote attacker can create a specially crafted .BMP file, trigger out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.


3) Out-of-bounds write (CVE-ID: CVE-2021-33657)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing .BMP files in video/SDL_pixels.c. A remote attacker can create a specially crafted BMP file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
