ZDI-26-464: GStreamer MRF File Parsing Heap-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-2026-18296.
AI Analysis
Technical Summary
CVE-2026-18296 is a heap-based buffer overflow vulnerability in GStreamer's MRF file parser caused by improper validation of the length of user-supplied data before copying it to a heap buffer. This flaw allows remote attackers to execute arbitrary code within the context of the affected process. Exploitation requires user interaction, such as opening a crafted file or visiting a malicious webpage. The vulnerability has 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 an update to fix this issue.
Potential Impact
Successful exploitation can lead to remote code execution with the privileges of the GStreamer process, potentially resulting in full compromise of the affected system or application. Confidentiality, integrity, and availability impacts are all rated high due to arbitrary code execution capabilities.
Mitigation Recommendations
GStreamer has issued an official update that corrects this vulnerability. Users and administrators should apply the update from the vendor advisory at https://gstreamer.freedesktop.org/security/sa-2026-0050.html to remediate this issue. No additional mitigation steps are indicated by the vendor.
