SB2018110647 - Fedora 29 update for mingw-SDL2_image

Description

This security bulletin contains information about 5 secuirty vulnerabilities.

1) Heap-based buffer overflow (CVE-ID: CVE-2018-3977)

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.

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

2) Stack-based buffer overflow (CVE-ID: CVE-2017-2887)

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

The vulnerability exists in the XCF property handling function of Simple DirectMedia Layer SDL_image due to stack-based buffer overflow. A remote attacker can send a specially crafted xcf file, trick the victim into opening it, trigger memory corruption and execute arbitrary code with privileges of the current user.

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

3) Out-of-bounds read (CVE-ID: CVE-2018-3837)

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists in the PCX image rendering functionality due to out-of-bounds read on the heap. A remote attacker can display a specially crafted PCX image, trick the victim into opening it and gain access to potentially sensitive information.

4) Out-of-bounds read (CVE-ID: CVE-2018-3838)

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists in the XCF image rendering functionality due to out-of-bounds read on the heap. A remote attacker can display a specially crafted XCF image, trick the victim into opening it and gain access to potentially sensitive information.

5) Out-of-bounds write (CVE-ID: CVE-2018-3839)

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

The weakness exists in the XCF image rendering functionality due to out-of-bounds write on the heap. A remote attacker can display a specially crafted XCF image, trick the victim into opening it and execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.
