## Overview

A flaw was found in GIMP. A stack buffer overflow vulnerability in the TIM image loader's 4BPP decoding path allows a local user to cause a Denial of Service (DoS). By opening a specially crafted TIM image file, the application crashes due to an unconditional overflow when writing to a variable-length array.

## Affected

- `gimp (all versions)`
- `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 issue, users should avoid opening untrusted TIM image files with GIMP. As a general security practice, users should exercise caution when handling files from unknown or suspicious sources.
