SB2019043001 - OpenSUSE Linux update for GraphicsMagick

Description

This security bulletin contains information about 6 secuirty vulnerabilities.

1) Stack-based buffer overflow (CVE-ID: CVE-2019-11005)

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 quoted font family value within the SVGStartElement() function in coders/svg.c in SVG reader. A remote unauthenticated attacker can create a specially crafted image, pass it to the affected application, 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.

2) Out-of-bounds read (CVE-ID: CVE-2019-11006)

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 function ReadMIFFImage of coders/miff.c in MIFF reader, which allows attackers to cause a denial of service or information disclosure via an RLE packet. A remote attacker can perform a denial of service attack.

3) 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.

4) 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.

5) Out-of-bounds read (CVE-ID: CVE-2019-11009)

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

6) Memory leak (CVE-ID: CVE-2019-11010)

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

The vulnerability exists due to memory leak within the function ReadMPCImage in coders/mpc.c, which allows attackers to cause a denial of service via a crafted image file. A remote attacker can perform a denial of service attack.
