Description OSIDB Bzimport 2026-10-08 14:30:18 UTC 
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.
