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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 component. It occurs when the GetList method is called with crafted input, causing the program to access memory after it has been freed. This leads to a crash and denial of service.

Detection Guidance

To detect this vulnerability, check the installed version of ImageMagick using the command: convert --version or identify --version. If the version is below 7.1.2-30 or 6.9.13-55, the system is vulnerable. Additionally, monitor for crashes or denial-of-service events when PerlMagick's GetList method is called.

Impact Analysis

The vulnerability can cause applications using affected ImageMagick versions to crash, resulting in denial of service. It requires local access and user interaction to trigger but does not allow code execution or data theft.

Compliance Impact

This vulnerability causes a denial of service through crashes but does not impact confidentiality or integrity of data. It does not directly violate GDPR or HIPAA compliance as it does not lead to data breaches or unauthorized access. However, repeated crashes could disrupt systems handling sensitive data, potentially affecting availability requirements under these regulations.

Mitigation Strategies

Update ImageMagick to version 7.1.2-30 or later for ImageMagick 7 and 6.9.13-55 or later for ImageMagick 6. This patch addresses the heap-use-after-free vulnerability in the GetList method of PerlMagick.
