MITRE ATT&CK
1 technique across 1 tactic: Execution The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Impact | The CVSS 3.1 score of 8.8 reflects a network-attackable vulnerability (AV:N) with low complexity (AC:L) that requires user interaction (UI:R) but no privileges (PR:N), potentially compromising confidentiality, integrity, and availability (C:H/I:H/A:H). While the high CVSS score indicates severe technical impact, the requirement for user interaction significantly reduces the real-world risk compared to wormable vulnerabilities. The vulnerability was reported through the Zero Day Initiative (ZDI-CAN-22873) and has available patches, suggesting responsible disclosure rather than active exploitation. Without EPSS data or KEV listing provided, there's no indication of active exploitation in the wild, positioning this as a priority for patching but not an emergency response scenario. |
| Exploit ScenarioDerived | An attacker could craft a malicious AV1-encoded video file with specially formatted tile list data that triggers the buffer overflow when processed by a vulnerable GStreamer installation. When a user opens this video file in any application using GStreamer (such as media players, video editors, or web browsers with GStreamer backends), the overflow could execute attacker-controlled code with the privileges of the running application. The attack requires convincing a user to open the malicious file, which could be delivered via email attachment, malicious website, or file-sharing platforms. |

Alert meAnalysisAIv1 – Mar 17, 2026
A stack-based buffer overflow vulnerability exists in GStreamer's AV1 video parsing functionality that allows remote attackers to execute arbitrary code when processing specially crafted AV1-encoded video files. The vulnerability affects all versions of GStreamer prior to the patched release and requires user interaction to exploit, such as opening a malicious video file. With a CVSS score of 8.8 and patches available since the disclosure, this represents a high-severity issue for applications using GStreamer for video processing.
RemediationAI
Apply the vendor-provided patch immediately by updating to a GStreamer version that includes commit f368d63ecd89e01fd2cf0b1c4def5fc782b2c390 or later (see https://gitlab.freedesktop.org/gstreamer/gstreamer/-/commit/f368d63ecd89e01fd2cf0b1c4def5fc782b2c390). Until patching is complete, consider implementing application-level controls to validate AV1 video sources, restrict processing of untrusted video files, and run GStreamer-based applications with minimal privileges. Organizations should also review the Zero Day Initiative advisory at https://www.zerodayinitiative.com/advisories/ZDI-24-567/ for additional technical details.

Technical ContextAI · show details
GStreamer is a widely-used open-source multimedia framework that provides libraries and tools for constructing graphs of media-handling components. The vulnerability (CWE-121: Stack-based Buffer Overflow) occurs specifically in the AV1 video codec parsing component when processing tile list data. The affected product is identified as cpe:2.3:a:gstreamer:gstreamer:*:*:*:*:*:*:*:* indicating all versions before the patch. The flaw stems from insufficient validation of user-supplied data length before copying it to a fixed-size stack buffer, a classic boundary error that can lead to memory corruption and code execution.

Lifecycle Timeline
2DescriptionCVE.org
GStreamer AV1 Video Parsing Stack-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 parsing of tile list data within AV1-encoded video files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22873.
Executive ViewAI
CVE-2024-0444 presents significant security risk, a stack-based buffer overflow vulnerability rated CVSS 8.8. Exploitation could allow attackers to corrupt memory, crash the application, or potentially execute arbitrary code. A patch is available and should be applied as part of regular vulnerability management.
Apply vendor patch. If immediate patching is not feasible: (1) Enable ASLR and DEP where available; (2) Implement network segmentation; (3) Monitor for exploitation indicators.

Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
