Description OSIDB Bzimport 2026-08-24 16:52:41 UTC 
A flaw was found in the file-pix (ESM) plugin in GIMP, affecting versions 3.0.0 and newer. When processing a specially crafted PIX image file, the plugin allocates a Variable-Length Array (VLA) on the stack without proper bounds checking, causing an unbounded stack allocation followed by a 21-byte stack over-read. This can result in a denial of service due to stack exhaustion and a limited information disclosure of stack memory contents into an intermediate file.
