Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-763: Release of Invalid Pointer or Reference, where the product attempts to return a memory resource to the system, but it calls the wrong release function or calls the appropriate release function incorrectly. In Magick.NET Q8 x64, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The BilateralBlurImage method will allocate a set of double buffers inside AcquireBilateralTLS. But 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.
