Description Laura Pardo 2026-10-27 11:11:53 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

ImageMagick before 7.1.2-33 contains a memory leak vulnerability in the MAT decoder that fails to release allocated memory in a specific error path. Attackers can supply crafted MAT files that trigger this error path repeatedly, causing small memory leaks that gradually consume process memory.
