1 technique across 1 tactic: Collection The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Impact | While the CVSS 3.0 score of 7.5 (High) reflects the potential for remote denial of service without authentication, the real-world risk appears moderate based on multiple signals. The EPSS score of 3.13% places it in the 87th percentile, suggesting above-average exploitation likelihood compared to other CVEs. The attack vector is network-based with low complexity and requires no privileges or user interaction (AV:N/AC:L/PR:N/UI:N), making it relatively easy to exploit. However, the impact is limited to availability (A:H) with no confidentiality or integrity impact. The vulnerability is not listed in CISA KEV, indicating no confirmed active exploitation. The presence of patches and multiple vendor advisories suggests this is a known issue that organizations should prioritize for patching, especially those processing untrusted media files. |
| Exploit ScenarioDerived | An attacker could host a malicious MP4 or QuickTime file on a web server or distribute it via email attachment. When a vulnerable GStreamer-based application (such as a media player or streaming service) attempts to parse the file's metadata tags, the out-of-bounds read triggers a crash, resulting in denial of service. Given the network attack vector and low complexity, this could be automated to target streaming services or media processing pipelines at scale. |

Alert meAnalysisAIv1 – Mar 17, 2026
A memory safety vulnerability in GStreamer's MP4/QuickTime demuxer allows remote attackers to trigger an out-of-bounds read when processing malformed tag values in media files. The vulnerability affects GStreamer versions before 1.10.3 and can cause application crashes when parsing specially crafted MP4/MOV files. With an EPSS score of 3.13% (87th percentile), this vulnerability has moderate exploitation likelihood in the wild.
RemediationAI
Upgrade GStreamer to version 1.10.3 or later as documented in the official GStreamer release notes at https://gstreamer.freedesktop.org/releases/1.10/#1.10.3. Linux distribution users should apply vendor-specific security updates: Debian users should reference DSA-3820, Red Hat users should apply RHSA-2017:2060, and Gentoo users should follow GLSA 201705-10. As a temporary mitigation until patching is complete, consider implementing input validation for media files from untrusted sources or isolating media processing operations in sandboxed environments to limit the impact of potential crashes.

Technical ContextAI · show details
The vulnerability exists in the qtdemux_tag_add_str_full function within the gst/isomp4/qtdemux.c component of the gst-plugins-good package in GStreamer multimedia framework (CPE: cpe:2.3:a:gstreamer:gstreamer:*:*:*:*:*:*:*:*). This function handles metadata tag parsing in ISO MP4/QuickTime format files. The root cause is a CWE-125 (Out-of-bounds Read) condition where the code fails to properly validate tag value boundaries before reading memory, leading to potential information disclosure through memory contents beyond the intended buffer.

Lifecycle Timeline
2DescriptionCVE.org
The qtdemux_tag_add_str_full function in gst/isomp4/qtdemux.c in gst-plugins-good in GStreamer before 1.10.3 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a crafted tag value.
Executive ViewAI
Organizations using gst/isomp4/qtdemux.c in gst-plugins-good in GStreamer face notable risk from CVE-2016-10199, a out-of-bounds read vulnerability rated CVSS 7.5. Exploitation could compromise the security of affected deployments. A patch is available and should be applied as part of regular vulnerability management.
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.
