Description
This security bulletin contains information about 12 vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2018-3977)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to heap-based buffer overflow in the XCF image rendering functionality. A remote unauthenticated attacker can supply a specially crafted XCF image, trigger memory corruption and execute arbitrary code with elevated privileges.

The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the IMG_LoadPCX_RW() function in IMG_pcx. A remote attacker can trick the victim to open a specially crafted file, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

The vulnerability exists due to a NULL pointer dreference error in SDL2_image function IMG_LoadPCX_RW at IMG_pcx.c. A remote attacker can perform a denial of service (DoS) attack.
5) Buffer overflow (CVE-ID: CVE-2019-12219)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to crash the application.
The vulnerability exists due to a boundary error when processing images in the SDL_SetError_REAL() function in SDL_error.c. A remote attacker can create a specially crafted image, trick the victim into opening it, trigger memory corruption and perform a denial of service (DoS) attack.
6) Out-of-bounds read (CVE-ID: CVE-2019-12220)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to an out-of-bounds read in libSDL2.a due to an out-of-bounds read in the SDL function SDL_FreePalette_REAL at video/SDL_pixels.c.
7) Buffer overflow (CVE-ID: CVE-2019-12221)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to crash the application.
The vulnerability exists due to a boundary error when processing images in the SDL_free_REAL() function at stdlib/SDL_malloc.c. A remote attacker can create a specially crafted image, trick the victim into opening it, trigger memory corruption and perform a denial of service (DoS) attack.
8) Out-of-bounds read (CVE-ID: CVE-2019-12222)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to an out-of-bounds read in libSDL2.a due to an out-of-bounds read in the function SDL_InvalidateMap at video/SDL_pixels.c.
9) Out-of-bounds read (CVE-ID: CVE-2019-13616)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 6.7 [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]
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to heap-based buffer over-read in the "BlitNtoN" function in the "video/SDL_blit_N.c" file when called from the "SDL_SoftBlit" function in the "video/SDL_blit.c" file. A remote attacker can trick a victim to open a specially crafted file and perform a denial of service attack.
10) Buffer overflow (CVE-ID: CVE-2019-5051)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
An exploitable heap-based buffer overflow vulnerability exists when loading a PCX file in SDL2_image, version 2.0.4. A missing error handler can lead to a buffer overflow and potential code execution. An attacker can provide a specially crafted image file to trigger this vulnerability.
11) Integer overflow (CVE-ID: CVE-2019-5052)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
An exploitable integer overflow vulnerability exists when loading a PCX file in SDL2_image 2.0.4. A specially crafted file can cause an integer overflow, resulting in too little memory being allocated, which can lead to a buffer overflow and potential code execution. An attacker can provide a specially crafted image file to trigger this vulnerability.
12) Heap out-of-bounds read (CVE-ID: CVE-2019-7635)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 6.7 [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]
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 Blit1to4 function. A remote attacker can trick the victim into accessing a crafted image file and perform a denial of service attack.
