Executive brief
ImageMagick, a widely used tool for processing and editing digital images, contains a flaw in how it handles certain image formats. An attacker can provide a specially crafted image file that bypasses security limits, causing the software to consume excessive system resources. This could lead to a denial-of-service, making the image processing service or the server hosting it unavailable to legitimate users.
Technical details
A vulnerability exists in the MNG coder of ImageMagick due to a missing check against the list limit policy. By providing a crafted MNG file, a remote attacker can force the application to read more images than permitted, leading to uncontrolled resource consumption (CWE-400), inefficient algorithmic complexity (CWE-407), or uncontrolled recursion (CWE-674). This can be exploited over the network without authentication or user interaction to cause a denial-of-service (DoS) condition. The issue is resolved in versions 6.9.13-47 and 7.1.2-22.
