# GIMP: crafted PowerVR file overflows heap buffer, enabling code execution

GIMP's file-pvr plug-in computes image buffer sizes with an integer overflow, so a crafted .pvr file causes a heap-based buffer overflow. An attacker who gets a user to open or preview that file can run arbitrary code or crash GIMP.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Run `gimp --version` on each workstation or image-processing host and compare with the fixed release in the vendor advisory
- Check whether the file-pvr plug-in is installed (unknown path in the sources)

## Fix

- Upgrade GIMP to the fixed release named in the vendor or distribution advisory (unknown in the sources)
- Until patched, do not open untrusted .pvr files in GIMP

## From the sources

A flaw was found in GIMP. An integer overflow occurs in the file-pvr plug-in when calculating memory buffer sizes for image dimensions. By tricking a user into opening or previewing a specially crafted PowerVR (.pvr) file, an attacker can trigger a heap-based buffer overflow, potentially leading to arbitrary code execution or a Denial of Service (DoS) via an application crash.
