SB2019062416 - OpenSUSE Linux update for ImageMagick

Description

This security bulletin contains information about 5 secuirty vulnerabilities.

1) Resource exhaustion (CVE-ID: CVE-2019-11470)

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

The vulnerability exists due to a lack of checks for insufficient image data in a file in the "ReadCINImage()" function, as defined in the "coders/cin.c" file. A remote attacker can send a specially crafted Cineon image with an incorrect claimed image size, trick a user into opening it, trigger resource exhaustion and perform a denial of service (DoS) attack.

2) Division by zero (CVE-ID: CVE-2019-11472)

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

ReadXWDImage in coders/xwd.c in the XWD image parsing component of ImageMagick 7.0.8-41 Q16 allows attackers to cause a denial-of-service (divide-by-zero error) by crafting an XWD image file in which the header indicates neither LSB first nor MSB first.

3) 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.

4) 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.

5) Out-of-bounds read (CVE-ID: CVE-2019-11598)

The vulnerability allows a remote attacker to access sensitive information or cause a denial of service (DoS) condition.

The vulnerability exists due to a boundary condition in the "WritePNMImage()" function in the "coders/pnm.c" file. A remote attacker can send a specially crafted image file (related to SetGrayscaleImage in MagickCore/quantize.c.), trick the victim into opening it, trigger out-of-bounds read error, get access to sensitive information or cause a DoS condition on the targeted system.
