Description
Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-2gq3-ww97-wfjm. This link is maintained to preserve external references.
Original Description
ImageMagick before 7.1.2-15 and 6.9.13-40 contains a heap use-after-free in the meta coder: when memory allocation fails, a single byte is written to a stale pointer. Remote attackers can trigger it by processing specially crafted image files, causing a denial of service.
Affected versions
NuGet
| Package | Vulnerable | Fixed in |
|---|---|---|
| Magick.NET-Q16-AnyCPU | < 14.10.3 |
14.10.3 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
Magick.NET-Q16-AnyCPU NuGet → 14.10.3
- dotnet
dotnet add package Magick.NET-Q16-AnyCPU --version 14.10.3

Weakness
CWE-416: Use After Free
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
How to prevent it
- Architecture and Design: Choose a language that provides automatic memory management.
- Implementation: When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.
