CVE-2026-22770 (GCVE-0-2026-22770)

Vulnerability from cvelistv5 – Published: 2026-01-20 00:48 – Updated: 2026-01-21 20:10

Title

ImageMagick vulnerable to Release of Invalid Pointer in BilateralBlur when memory allocation fails

Summary

ImageMagick is free and open-source software used for editing and manipulating digital images. The BilateralBlurImage method will allocate a set of double buffers inside AcquireBilateralTLS. But, in versions prior to 7.1.2-13, the last element in the set is not properly initialized. This will result in a release of an invalid pointer inside DestroyBilateralTLS when the memory allocation fails. Version 7.1.2-13 contains a patch for the issue.

Severity

6.5 (Medium)

Mitigation

Phase: Implementation

Description:

Only call matching memory management functions. Do not mix and match routines. For example, when you allocate a buffer with malloc(), dispose of the original pointer with free().

Mitigation

Phase: Implementation

Description:

When programming in C++, consider using smart pointers provided by the boost library to help correctly and consistently manage memory.

Mitigation ID: MIT-4.6

Phase: Architecture and Design

Strategy: Libraries or Frameworks

Description:

Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
For example, glibc in Linux provides protection against free of invalid pointers.

Mitigation

Phase: Architecture and Design

Description:

Use a language that provides abstractions for memory allocation and deallocation.
