AnalysisAIv1 – Mar 12, 2026

ImageMagick versions prior to 7.1.2-13 fail to properly initialize buffer elements in the BilateralBlurImage method, leading to invalid pointer dereference and potential denial of service when memory allocation fails. An attacker can exploit this through network vectors to crash affected applications or trigger undefined behavior with high complexity requirements. A patch is available in version 7.1.2-13 and later.

Earlier versions of this analysis (1)
v1 Mar 12, 2026 - 21:54 CVSS 6.5

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. [CVSS 6.5 MEDIUM]

RemediationAI

A vendor patch is available — apply it immediately. Restrict network access to the affected service where possible.

Affects Imagemagick. 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.
