ImageMagick 7.1.2-31/6.9.13-56 policy bypass in PCD/CUBE/HALD coders
CVE-2026-93587 Published on September 18, 2026
ImageMagick before 7.1.2-31 Policy Bypass via PCD decoder
ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a policy bypass in the PCD (and, per the upstream advisory, CUBE and HALD) coder: when a specific command line option is supplied, the decoder does not check a configured resource limit, which can result in extra memory allocation. A local user able to pass command line options to ImageMagick can therefore exceed the intended memory policy limit, causing a limited availability impact. The issue is fixed in 7.1.2-31 and 6.9.13-56.
