GStreamer, a popular framework for building media-handling applications, has been found to have a medium severity vulnerability identified as CVE-2024-47597. This vulnerability allows for an out-of-bounds (OOB) read in the function qtdemux_parse_samples within qtdemux.c. The issue occurs when this function attempts to read data beyond the boundaries of the stream->stco buffer. Specifically, this flaw can lead to reading up to 8 bytes of data out-of-bounds, potentially compromising the integrity of the application and causing unexpected behavior.
The vulnerability was published on December 12, 2024, and has been classified with a CVSS score of 5.1, indicating its medium severity. Although this vulnerability is not considered critical, it poses a significant risk, especially for applications that utilize GStreamer to process media content. Organizations should prioritize applying the fix included in version 1.24.10, which addresses this vulnerability.
Currently, there is no confirmed public exploit available for this vulnerability, and it is not included in the Known Exploited Vulnerabilities (KEV) catalog. However, the existence of this OOB-read vulnerability should not be taken lightly, as it can still be leveraged by attackers in specific conditions, impacting systems that rely on GStreamer.
Organizations should prioritize patching immediately to prevent any potential exploitation of this vulnerability. Implementing the latest updates and conducting thorough testing can help ensure the integrity and security of media applications that utilize GStreamer.
Vulnerability Details
The official description of CVE-2024-47597 notes that an OOB-read has been detected in the function qtdemux_parse_samples within qtdemux.c, resulting from the function reading data beyond the stream->stco buffer. This vulnerability is categorized under CWE-125: Out-of-bounds Read.
The vulnerability has a CVSS score of 5.1, which classifies it as medium severity. The attack vector is classified as local, and the attack complexity is low, meaning that an attacker does not require significant resources to exploit this vulnerability. There are no privileges required, and user interaction is not necessary.
The affected product is GStreamer, specifically versions prior to 1.24.10, which includes all versions of GStreamer that are vulnerable. The vulnerability was first disclosed on December 12, 2024.
Technical Analysis
The root cause of CVE-2024-47597 is the improper handling of data boundaries within the qtdemux_parse_samples function. This function processes media samples and, due to a flaw in the code, attempts to access memory beyond the allocated buffer, which can lead to an OOB-read condition.
The attack vector for this vulnerability is local, as it requires access to the GStreamer application running on the machine. The complexity of the attack is low, meaning that an attacker can exploit the vulnerability with minimal effort. There are no privileges required to exploit this vulnerability, and no user interaction is necessary.
The impact of this vulnerability on confidentiality is none, while the integrity is impacted at a low level, as this type of vulnerability can lead to unintended behavior in applications. The availability impact is also low, indicating that the vulnerability does not cause a complete denial of service, but may lead to crashes or instability in the application.
Risk & Impact Analysis
The risk to organizations includes potential data exposure and application instability due to the OOB-read vulnerability in GStreamer. While the attack requires local access to the affected systems, it still represents a considerable risk for organizations that utilize GStreamer for media processing.
Given its medium severity rating, organizations should address this vulnerability in their priority patch cycle. The potential for attackers to leverage this flaw, combined with the low complexity of exploitation, makes it essential for organizations to take proactive measures to mitigate associated risks.
Organizations that have deployed GStreamer should assess their exposure, particularly in environments where media processing is critical. The urgency to remediate is medium, as the vulnerability does not pose immediate catastrophic risks, but it can still lead to negative impacts if left unaddressed.

Affected Versions
All versions of GStreamer prior to 1.24.10 are affected by this vulnerability. Organizations should ensure that they upgrade to the latest version to mitigate potential risks.
Mitigation & Remediation
To address CVE-2024-47597, organizations must upgrade GStreamer to version 1.24.10 or later. This version includes the necessary fixes to resolve the out-of-bounds read vulnerability.
If immediate upgrading is not feasible, organizations should consider implementing workarounds, such as applying stricter input validation and monitoring buffer accesses to detect potential anomalies.
Detection Guidance
Organizations should monitor logs for unusual access patterns or errors related to media processing that may indicate an attempt to exploit this vulnerability. Behavioral anomalies during media playback or processing should also be investigated.
Network signatures associated with GStreamer components can be beneficial for detecting potential exploitation attempts. Additionally, system changes made during GStreamer updates should be logged and monitored to ensure that no unauthorized modifications occur.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2024-47597 lies in the potential for similar vulnerabilities to be discovered in other media processing libraries. This highlights the importance of thorough code reviews and testing practices.
Organizations can learn from this incident by implementing a robust vulnerability management program that emphasizes proactive detection and remediation of vulnerabilities. Regular training for development teams on secure coding practices can significantly reduce the likelihood of similar vulnerabilities emerging.
Strategic defensive takeaways include the necessity of integrating security into the software development lifecycle. For more insights on vulnerability management, organizations can explore vulnerability management best practices to ensure ongoing security.
