Technical details
The vulnerability exists in the file-pix (ESM) plugin in GIMP due to improper bounds checking on a Variable-Length Array (VLA) allocated on the stack. When processing a specially crafted PIX image file, the plugin performs unbounded stack allocation followed by a 21-byte stack over-read. This results in a stack exhaustion condition that causes denial of service and limited information disclosure of stack memory contents into an intermediate file. The attack requires user interaction (opening a malicious PIX file) and affects local GIMP instances.
