Description Vladimir Vasilev 2026-10-09 08:51:17 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 7.1.2-30 and 6.9.13-55 contains an uncontrolled recursion vulnerability in the CALS decoder due to a missing depth check. Attackers can supply a crafted CALS image that triggers unbounded recursion, exhausting the stack and crashing the process, resulting in a denial of service.
