CVE-2026-18297: GStreamer OGG File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability
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.

Frequently Asked Questions
Does an attacker need an existing account or privileges on the target system?
No prior privileges are required according to the CVSS vector (PR:N). Exploitation still requires the target to visit a malicious page or open a malicious file containing crafted OGG data.
Does successful exploitation cross a separate security boundary?
The CVSS vector indicates unchanged scope (S:U). Any code execution occurs in the context of the process that parses the malicious OGG content.
