DescriptionCVE.org

GStreamer JPEG Parser Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation.

The specific flaw exists within the processing of Huffman tables. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28840.

AnalysisAI

Heap-based buffer overflow vulnerability in the GStreamer multimedia framework's JPEG parser that allows remote code execution when processing malicious Huffman tables. The vulnerability affects all versions of GStreamer (CPE shows wildcard versioning) and requires user interaction to exploit, with a CVSS score of 7.8. No active exploitation in the wild has been reported (not in KEV), and no EPSS data is available.

Technical ContextAI

GStreamer is an open-source multimedia framework used across Linux distributions and applications for media processing. The vulnerability (CWE-122: Heap-based Buffer Overflow) occurs in the JPEG parser component when processing Huffman tables - a critical part of JPEG compression. The flaw stems from insufficient validation of user-supplied data length before copying to a fixed-size heap buffer. Based on the CPE string (cpe:2.3:a:gstreamer:gstreamer:*:*:*:*:*:*:*:*), all GStreamer versions are potentially affected. The vulnerability was originally tracked as ZDI-CAN-28840 by Zero Day Initiative.

RemediationAI

A patch is available via GitLab commit 7d3c258ed928cf59d126c8ea926b185f046f444c in the GStreamer repository. Users should update to a GStreamer version containing this fix. As a temporary mitigation, restrict processing of untrusted JPEG files through GStreamer or implement input validation for JPEG content. Monitor the official GStreamer GitLab repository (https://gitlab.freedesktop.org/gstreamer/gstreamer/) for release notes indicating which versions include this security fix.
