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 9.8 reflects the vulnerability's network-exploitable nature (AV:N), low complexity (AC:L), and lack of required privileges (PR:N) or user interaction (UI:N), with high impact across confidentiality, integrity, and availability. The vulnerability allows remote code execution through malicious media files, making it particularly dangerous for web applications, media servers, and any software processing untrusted media content. While no EPSS score or KEV listing is mentioned, the availability of detailed technical analysis from GitHub Security Lab and active patching by both upstream and downstream vendors (including Debian) indicates this is a real-world concern. The automatable nature of exploitation via crafted media files and the technical impact of arbitrary code execution align with critical SSVC prioritization. |
| Exploit ScenarioDerived | An attacker crafts a malicious QuickTime media file with a specially formed Theora extension that triggers the integer underflow when parsed by GStreamer. When a vulnerable application processes this file (such as a media server transcoding user uploads or a web browser playing embedded video), the memory corruption allows the attacker to hijack execution flow and run arbitrary code with the privileges of the GStreamer process. Given the network attack vector and lack of authentication requirements, this could be exploited through web uploads, email attachments, or any service accepting media files. |

Alert meAnalysisAIv1 – Mar 17, 2026
A critical integer underflow vulnerability in GStreamer's QuickTime demuxer (qtdemux) leads to memory corruption and arbitrary code execution when processing specially crafted media files. The vulnerability affects all GStreamer versions prior to 1.24.10, allowing remote attackers to execute arbitrary code without authentication by providing malicious media content. With a CVSS score of 9.8 and patches available, this represents a severe risk for applications using GStreamer for media processing.
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/8032.patch. Debian users should apply the security updates referenced in debian-lts-announce messages from December 2024 and February 2025. Until patching is possible, avoid processing untrusted media files with GStreamer-based applications, particularly QuickTime format files containing Theora video streams. Organizations should review the vendor advisory at https://gstreamer.freedesktop.org/security/sa-2024-0014.html and the detailed analysis at https://securitylab.github.com/advisories/GHSL-2024-166_Gstreamer/ for additional context.

Technical ContextAI · show details
GStreamer is a widely-used open-source multimedia framework for constructing media-handling pipelines, identified by CPE cpe:2.3:a:gstreamer:gstreamer. The vulnerability occurs in the qtdemux_parse_theora_extension function within qtdemux.c, where an integer underflow (CWE-190) causes a gint size variable to underflow to a large negative value. When this negative 32-bit value is cast to a 64-bit unsigned integer (0xfffffffffffffffa) during memory allocation, it triggers a chain of errors: the allocation size overflows during alignment calculations, resulting in only 0x89 bytes being allocated instead of the requested amount. This leads to a heap buffer overflow during subsequent memcpy operations, ultimately corrupting function pointers in the GstMapInfo structure that can be hijacked during memory unmapping operations.

2DescriptionGitHub Advisory
GStreamer is a library for constructing graphs of media-handling components. An integer underflow has been detected in the function qtdemux_parse_theora_extension within qtdemux.c. The vulnerability occurs due to an underflow of the gint size variable, which causes size to hold a large unintended value when cast to an unsigned integer. This 32-bit negative value is then cast to a 64-bit unsigned integer (0xfffffffffffffffa) in a subsequent call to gst_buffer_new_and_alloc. The function gst_buffer_new_allocate then attempts to allocate memory, eventually calling _sysmem_new_block. The function _sysmem_new_block adds alignment and header size to the (unsigned) size, causing the overflow of the 'slice_size' variable. As a result, only 0x89 bytes are allocated, despite the large input size. When the following memcpy call occurs in gst_buffer_fill, the data from the input file will overwrite the content of the GstMapInfo info structure. Finally, during the call to gst_memory_unmap, the overwritten memory may cause a function pointer hijack, as the mem->allocator->mem_unmap_full function is called with a corrupted pointer. This function pointer overwrite could allow an attacker to alter the execution flow of the program, leading to arbitrary code execution. This vulnerability is fixed in 1.24.10.
Executive ViewAI
Organizations using GStreamer face critical risk from CVE-2024-47606, a integer overflow 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) Implement network-level access controls to limit exposure; (2) Enable enhanced monitoring and alerting; (3) Apply principle of least privilege.
