CVE-2026-3082 · Severity: high · CVSS 7.8 · Published 2026-03-16

GStreamer is a widely used multimedia framework for processing audio and video data. A security vulnerability in its JPEG image processing component could allow an attacker to execute malicious code on a user's system if they are tricked into opening a specially crafted image file. This could lead to a full system compromise, data theft, or unauthorized access to the user's environment.

## Technical details

A heap-based buffer overflow exists in the GStreamer 'gst-plugins-bad' package within the JPEG parsing logic. The vulnerability is caused by a lack of proper validation of the length of user-supplied data during the processing of Huffman tables before it is copied into a fixed-length heap buffer. An attacker can exploit this by providing a specially crafted JPEG file that, when processed by an application using the GStreamer library, triggers the overflow. This can lead to arbitrary code execution within the context of the application process. The issue has been addressed in GStreamer version 1.28.1 by implementing proper bounds checking.

## Affected products

- GStreamer GStreamer gst-plugins-bad versions prior to 1.28.1
- Red Hat Enterprise Linux 8, 9, 10, 10.2
