ZDI-26-465: 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 ZDI has assigned a CVSS rating of 7.8. The following CVEs are assigned: CVE-2026-18297.
AI Analysis
Technical Summary
CVE-2026-18297 is a stack-based buffer overflow vulnerability in GStreamer's OGG file parser. The vulnerability occurs due to insufficient validation of the length of user-supplied data before copying it to a stack buffer, enabling remote attackers to execute arbitrary code within the context of the current process. Exploitation requires user interaction, such as opening a crafted OGG file or visiting a malicious webpage. The Zero Day Initiative assigned a CVSS score of 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). GStreamer has released a security update to fix this vulnerability.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary code with the privileges of the affected process, potentially leading to full compromise of the system running GStreamer. The attack requires user interaction but can result in complete confidentiality, integrity, and availability impact.
Mitigation Recommendations
GStreamer has issued an official update that corrects this vulnerability. Users and administrators should apply the security update provided by GStreamer as soon as possible to remediate this issue. No additional mitigation steps are specified beyond applying the vendor's update.
