SB2019051004 - OpenSUSE Linux update for GraphicsMagick

Description

This security bulletin contains information about 6 secuirty vulnerabilities.

1) 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.

2) 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.

3) Out-of-bounds read (CVE-ID: CVE-2019-11473)

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

The vulnerability exists due to a boundary condition within the ReadXWDImage() function in coders/xwd.c in XWD reader. A remote attacker can create a specially crafted XWD image file, pass it to the affected application, trigger out-of-bounds read error and crash the application.

4) Incorrect calculation (CVE-ID: CVE-2019-11474)

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

The vulnerability exists due to incorrect calculation within the ReadXWDImage() function in coders/xwd.c in XWD reader. A remote attacker can create a specially crafted XWD file, pass it to the application, trigger a floating-point exception and crash the affected application.

5) Heap-based buffer overflow (CVE-ID: CVE-2019-11505)

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

The vulnerability exists due to a boundary error in function WritePDBImage() in coders/pdb.c. A remote attacker can create a specially crafted image file, pass it to the affected 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.

6) Heap-based buffer overflow (CVE-ID: CVE-2019-11506)

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

The vulnerability exists due to a boundary error in MAT writer within the function WriteMATLABImage of coders/mat.c, related to ExportRedQuantumType in magick/export.c. A remote attacker can create a crafted image file, pass it to the affected 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.
