## Overview

A flaw was found in the GStreamer JPEG 2000 decimator in gst-plugins-bad. Crafted JPEG 2000 media can cause integer overflows or division by zero during tile processing. An application that processes the malicious media may crash, resulting in a denial of service.

## Affected

- `gstreamer1-plugins-bad-free (all versions)`
- `gstreamer1-plugins-bad-free (all versions)`
- `gstreamer1-plugins-bad-free (all versions)`
- `gstreamer1-plugins-bad-free (all versions)`

## Remediation

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

### Workarounds

Applications that do not require JPEG 2000 decimation can avoid using the jp2kdecimator element and reject untrusted JPEG 2000 media before it reaches a pipeline that uses this element.
