Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2019-10650)

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 WriteTIFFImage() function in coders/tiff.c, which allows an attacker to cause a denial of service or information disclosure via a crafted image file. A remote attacker can perform a denial of service attack.


2) Out-of-bounds read (CVE-ID: CVE-2019-11007)

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 ReadMNGImage function of coders/png.c, which allows attackers to cause a denial of service or information disclosure via an image colormap. A remote attacker can perform a denial of service attack.


3) Heap-based buffer overflow (CVE-ID: CVE-2019-11008)

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

The vulnerability exists due to a boundary error within the WriteXWDImage() function in coders/xwd.c. A remote attacker can create a crafted XWD file, pass it to the application, trigger 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.


4) Stack-based buffer overflow (CVE-ID: CVE-2019-9956)

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

The vulnerability exists due to a boundary error when processing a crafted image file in the PopHexPixel() function of coders/ps.c. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

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