Description
This security bulletin contains information about 4 vulnerabilities.
1) Heap out-of-bounds read (CVE-ID: CVE-2019-7637)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to heap-based buffer over-read condition in the SDL_FillRect function. A remote attacker can trick the victim into accessing a crafted image file and perform a denial of service attack.
2) Integer overflow (CVE-ID: CVE-2020-14409)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
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.
3) Out-of-bounds read (CVE-ID: CVE-2020-14410)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the "Blit_3or4_to_3or4__inversed_rgb" in "video/SDL_blit_N.c". 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.
4) Out-of-bounds write (CVE-ID: CVE-2021-33657)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
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.
