CVE-2017-12430

In ImageMagick 7.0.6-1, a memory exhaustion vulnerability was found in the function ReadMPCImage in coders/mpc.c, which allows attackers to cause a denial of service.

This update for ImageMagick fixes several issues.

These security issues were fixed:

• CVE-2017-1000476: A CPU exhaustion vulnerability was found in the function ReadDDSInfo in coders/dds.c, which allowed attackers to cause a denial of service (bsc#1074610).

It was discovered that ImageMagick incorrectly handled certain malformed image files. If a user or automated system using ImageMagick were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program.
