CVE-2026-18297

A flaw was found in GStreamer. This vulnerability, a stack-based buffer overflow, occurs during the parsing of OGG files due to improper validation of user-supplied data length. A remote attacker could exploit this by tricking a user into visiting a malicious page or opening a malicious file, leading to arbitrary code execution within the context of the current process.

7.8 (High)

CVE-2026-18297 (GCVE-0-2026-18297)

Vulnerability from cvelistv5 – Published: 2026-08-20 16:22 – Updated: 2026-08-21 03:57

Title

GStreamer OGG File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability

Summary

GStreamer OGG File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of OGG files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-29584.
