Technical details

A heap-based buffer overflow (CWE-787) exists in ImageMagick's 'fx' operation. The vulnerability is triggered when the software processes a specially crafted argument, leading to an out-of-bounds write on the heap. Exploitation requires a local attacker with low privileges and some degree of user interaction (e.g., convincing a user to process a malicious file). The primary impact is on system availability, potentially causing a crash (DoS). The issue is resolved in version 7.1.2-27.
