| Impact | Despite the critical CVSS 9.8 score indicating network-exploitable, no-authentication-required remote code execution potential, the real-world risk requires nuanced assessment. The vulnerability is not listed in CISA's KEV catalog, suggesting no known active exploitation in the wild. The attack vector requires processing specially crafted media files, which adds a layer of complexity compared to direct network services. However, the high impact ratings (Confidentiality/Integrity/Availability all High) and the fact that GStreamer processes untrusted media content in many contexts (web browsers, media players, streaming servers) make this a significant concern. The availability of detailed technical information and patches suggests this could become exploitable if left unpatched, particularly in internet-facing applications that process user-supplied media. |
| Exploit ScenarioDerived | An attacker could craft a malicious MP4 media file with specific metadata that triggers the out-of-bounds write when processed by a vulnerable GStreamer instance. When a user opens this file in a media player or when a web service processes it automatically, the 3-byte overflow could potentially be leveraged to corrupt memory structures and achieve code execution. Given the network attack vector and lack of required authentication, this could be delivered via web downloads, email attachments, or streaming services that process user uploads. |

Alert meAnalysisAIv1 – Mar 17, 2026
An out-of-bounds write vulnerability in GStreamer's isomp4/qtdemux.c allows remote attackers to overwrite up to 3 bytes beyond allocated memory boundaries when processing media files. The vulnerability affects all GStreamer versions prior to 1.24.10 and can be exploited without authentication over the network, potentially leading to remote code execution. While no active exploitation has been reported (not in KEV), the vulnerability has a critical CVSS score of 9.8 and patches are available.
RemediationAI
Upgrade GStreamer to version 1.24.10 or later, which contains the fix for this vulnerability. The patch is available at https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/8059.patch and should be applied immediately to all affected systems. For systems that cannot be immediately upgraded, consider implementing network-level filtering to block untrusted media files from being processed by GStreamer-based applications, particularly for internet-facing services. Debian users should refer to the security announcement at https://lists.debian.org/debian-lts-announce/2025/02/msg00035.html for distribution-specific patches.

Technical ContextAI · show details
GStreamer is a widely-used open-source multimedia framework for constructing media-handling pipelines, commonly deployed in Linux distributions, media players, and streaming applications. The vulnerability (CWE-787: Out-of-bounds Write) occurs in the convert_to_s334_1a function within the ISO MP4 demultiplexer component, where a logic error causes misalignment between allocated memory size and loop iteration bounds when ccpair_size is an even number. Based on the CPE identifier (cpe:2.3:a:gstreamer:gstreamer:*:*:*:*:*:*:*:*), all versions of GStreamer prior to 1.24.10 are affected, making this a widespread issue across numerous media processing applications.

Lifecycle Timeline
2DescriptionGitHub Advisory
GStreamer is a library for constructing graphs of media-handling components. An out-of-bounds write vulnerability was identified in the convert_to_s334_1a function in isomp4/qtdemux.c. The vulnerability arises due to a discrepancy between the size of memory allocated to the storage array and the loop condition i * 2 < ccpair_size. Specifically, when ccpair_size is even, the allocated size in storage does not match the loop's expected bounds, resulting in an out-of-bounds write. This bug allows for the overwriting of up to 3 bytes beyond the allocated bounds of the storage array. This vulnerability is fixed in 1.24.10.
Executive ViewAI
Organizations using GStreamer face critical risk from CVE-2024-47539, a out-of-bounds write vulnerability rated CVSS 9.8. Exploitation could allow attackers to corrupt memory, crash the application, or potentially execute arbitrary code. A patch is available and should be applied immediately given the critical severity.
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.
