## Overview

A flaw was found in the file-xwd plugin in GIMP. When processing a specially crafted XWD image file, the plugin validates the image width and bytes-per-line parameters independently rather than ensuring their combined values are consistent with the allocated buffer size. This incorrect validation leads to improper bounds checking, causing a heap out-of-bounds read. This issue can result in an application crash, leading to a denial of service or a limited information disclosure of heap memory contents into the produced image.

## Affected

- `gimp (all versions)`
- `gimp`
- `gimp (all versions)`
- `gimp:2.8/gimp (all versions)`
- `gimp (all versions)`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.

### Workarounds

To mitigate this vulnerability, do not open XWD files from untrusted sources with GIMP.
