CVE-2025-70308 is a security vulnerability identified in the GPAC multimedia framework version 2.4.0, specifically within the GSF demuxer filter component. The flaw is an out-of-bounds read error triggered by processing a specially crafted .gsf file. An out-of-bounds read occurs when the software reads data outside the allocated memory buffer, which can lead to application crashes or undefined behavior. In this case, the vulnerability results in a Denial of Service (DoS) condition, where the affected application or system component can be forced to crash or become unresponsive, disrupting normal operations. The vulnerability does not currently have a CVSS score, and no public exploits have been reported. Exploitation requires the victim to process a malicious .gsf file, which may occur through user interaction or automated media processing workflows. The vulnerability affects the availability of the system by causing crashes but does not appear to allow code execution or data leakage. GPAC is widely used in multimedia applications for media packaging, streaming, and playback, making this vulnerability relevant to organizations handling media content. The lack of a patch or mitigation details suggests that users should monitor for updates from GPAC maintainers and consider interim protective measures.

For European organizations, the primary impact of CVE-2025-70308 is service disruption due to Denial of Service attacks targeting media processing pipelines that utilize GPAC. This can affect broadcasters, streaming service providers, media production companies, and any enterprise relying on GPAC for multimedia content handling. Disruptions could lead to downtime, loss of service availability, and potential reputational damage. In critical environments such as live broadcasting or media delivery platforms, this could translate into significant operational and financial losses. Since the vulnerability requires processing a crafted .gsf file, attackers might exploit publicly accessible media upload or processing services, or target internal workflows that handle untrusted media files. The impact on confidentiality and integrity appears minimal, but availability degradation can have cascading effects on business continuity and customer trust.

1. Monitor GPAC official channels for security updates and apply patches promptly once available. 2. Until a patch is released, restrict or disable processing of untrusted .gsf files in media workflows. 3. Implement strict input validation and sanitization for media files entering the system to detect and block malformed .gsf files. 4. Use sandboxing or containerization techniques to isolate media processing components, limiting the impact of crashes. 5. Employ runtime monitoring and automated recovery mechanisms to detect and restart failed media processing services quickly. 6. Review and harden access controls on media upload and processing interfaces to reduce exposure to crafted files. 7. Conduct security awareness training for staff handling media ingestion to recognize suspicious files.
