Technical details

An off-by-one error (CWE-193) exists in the morphology validation component of ImageMagick. The vulnerability is triggered when the software processes incorrect morphology parameters, leading to an out-of-bounds read (CWE-125) on the heap. Specifically, the flaw allows for a single-pixel memory access violation. While the impact is primarily limited to a denial-of-service (application crash), exploitation requires a local attacker to convince a user to process a malicious input (User Interaction Required). The issue is resolved in versions 7.1.2-19 and 6.9.13-44.
