SB2019091669 - Fedora 29 update for SDL2_image

Description

This security bulletin contains information about 7 secuirty vulnerabilities.

1) Buffer overflow (CVE-ID: CVE-2019-12221)

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.

2) Heap-based buffer overflow (CVE-ID: CVE-2019-12216)

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.

3) NULL pointer dereference (CVE-ID: CVE-2019-12217)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dreference error in SDL stdio_read function in file/SDL_rwops.c. A remote attacker can perform a denial of service (DoS) attack.

4) NULL pointer dereference (CVE-ID: CVE-2019-12218)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

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)

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)

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) Out-of-bounds read (CVE-ID: CVE-2019-12222)

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.
