CVE-2026-105401
ImageMagick before 7.1.2-31 Heap Buffer Overflow in Distributed Pixel Cache Server
Description
ImageMagick before 7.1.2-31 contains a heap buffer overflow vulnerability in the distributed pixel cache server that allows connecting clients to overwrite heap memory by sending crafted data. Attackers can connect to the distributed pixel cache server and transmit malicious data to trigger a heap buffer over-write that crashes the server, causing denial of service.
