| Impact | Despite the critical CVSS score of 9.1, the real-world risk requires nuanced assessment. The CVSS vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H) indicates network-exploitable with no authentication required and low complexity, suggesting high exploitability. However, the impact is limited to confidentiality (reading 8 bytes) and availability (potential crashes), with no integrity impact. The vulnerability is not listed in CISA's KEV catalog indicating no known active exploitation, and no EPSS score is provided to gauge exploitation probability. The existence of a public proof-of-concept (GHSL-2024-245_crash1.mp4) increases the likelihood of exploitation attempts. For applications processing untrusted media files from the internet, this represents a high-priority issue, while internal media processing systems with controlled inputs face lower risk. |
| Exploit ScenarioDerived | An attacker hosts a malicious MP4 file (similar to the disclosed GHSL-2024-245_crash1.mp4 proof-of-concept) on a web server and tricks users into streaming or downloading it through a vulnerable GStreamer-based media player. When the application attempts to parse the specially crafted stco atoms in the MP4 container, it reads 8 bytes beyond the allocated buffer, potentially exposing sensitive memory contents like authentication tokens or causing the application to crash. Given the network attack vector and low complexity, this could be automated for large-scale attacks against streaming services or media processing pipelines. |

Alert meAnalysisAIv1 – Mar 17, 2026
An out-of-bounds read vulnerability exists in GStreamer's MP4 demuxer that allows remote attackers to read up to 8 bytes beyond allocated memory boundaries when processing malformed MP4 files. The vulnerability affects all GStreamer versions prior to 1.24.10 and can be triggered without authentication by serving a malicious MP4 file, potentially exposing sensitive memory contents or causing application crashes. A proof-of-concept file (GHSL-2024-245_crash1.mp4) has been publicly disclosed, and while not currently in CISA's KEV catalog, the vulnerability has a critical CVSS score of 9.1.
RemediationAI
Upgrade GStreamer to version 1.24.10 or later, which contains the security fix available at https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/8059.patch. For systems that cannot immediately upgrade, implement input validation to reject untrusted MP4 files or isolate media processing in sandboxed environments with restricted memory access. Organizations should review the vendor advisory at https://gstreamer.freedesktop.org/security/sa-2024-0012.html for distribution-specific patches and monitor https://lists.debian.org/debian-lts-announce/2025/02/msg00035.html for updates if using Debian-based systems.

Technical ContextAI · show details
GStreamer is a widely-used open-source multimedia framework library for constructing graphs of media-handling components, identified by CPE cpe:2.3:a:gstreamer:gstreamer:*:*:*:*:*:*:*:*. The vulnerability manifests as a CWE-125 (Out-of-bounds Read) in the qtdemux_parse_samples function within qtdemux.c, specifically when calling qt_atom_parser_get_offset_unchecked to parse Sample Table Chunk Offset (stco) atoms in MP4/QuickTime files. This buffer overflow occurs when the parser attempts to read offset data beyond the boundaries of the stream->stco buffer, a classic boundary checking failure that allows reading adjacent memory locations.

Lifecycle Timeline
2DescriptionGitHub Advisory
GStreamer is a library for constructing graphs of media-handling components. An OOB-read has been detected in the function qtdemux_parse_samples within qtdemux.c. This issue arises when the function qtdemux_parse_samples reads data beyond the boundaries of the stream->stco buffer. The following code snippet shows the call to qt_atom_parser_get_offset_unchecked, which leads to the OOB-read when parsing the provided GHSL-2024-245_crash1.mp4 file. This issue may lead to read up to 8 bytes out-of-bounds. This vulnerability is fixed in 1.24.10.
Executive ViewAI
Organizations using GStreamer face critical risk from CVE-2024-47597, a out-of-bounds read vulnerability rated CVSS 9.1. Successful exploitation could critically impact the confidentiality, integrity, and availability of affected systems. A patch is available and should be applied immediately given the critical severity.
Apply vendor patch. If immediate patching is not feasible: (1) Implement network-level access controls to limit exposure; (2) Enable enhanced monitoring and alerting; (3) Apply principle of least privilege.

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.
Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
