CWE ID Description
CWE-416 The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Executive Summary

This is a heap-use-after-free vulnerability in ImageMagick's PerlMagick Layer method. It occurs when an attacker provides a specially crafted list of images, causing memory to be accessed after it has been freed. This leads to crashes or denial of service.

Detection Guidance

To detect this vulnerability, check the installed version of ImageMagick using the command: identify -version or convert -version. If the output shows a version before 7.1.2-30 or 6.9.13-55, the system is vulnerable.

Impact Analysis

The vulnerability can cause crashes or denial of service when processing images. It requires local access and user interaction but does not affect confidentiality or integrity. The impact is limited to system availability.

Mitigation Strategies

Immediately update ImageMagick to version 7.1.2-30 or later for ImageMagick 7, or 6.9.13-55 or later for ImageMagick 6. This patch resolves the heap-use-after-free issue in the Layer method of PerlMagick.
