CVE-2026-3082 — GStreamer JPEG Parser Heap-based Buffer Overflow Remote Code Execution Vulnerability

Description (CNA)

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.

A flaw was found in GStreamer. A remote attacker can exploit a heap-based buffer overflow vulnerability in the GStreamer JPEG parser by providing a specially crafted JPEG file. This issue is caused by improper validation of Huffman table lengths, which can lead to arbitrary code execution in the context of the current process.
