Doc Text:
A flaw was found in ImageMagick. The BilateralBlurImage method improperly initializes a memory buffer. This can lead to the release of an invalid pointer if memory allocation fails. A remote attacker could exploit this vulnerability to cause a Denial of Service (DoS) by providing a specially crafted image, leading to application instability or crashes.

Description OSIDB Bzimport 2026-01-20 02:01:28 UTC
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.
