CVE-2024-35368 is a critical vulnerability identified in FFmpeg version 7.0, a widely used open-source multimedia framework. The issue arises from a double free condition in the rkmpp_retrieve_frame function located in the libavcodec/rkmppdec.c source file. Double free vulnerabilities occur when a program attempts to free the same memory location more than once, leading to undefined behavior such as memory corruption, crashes, or arbitrary code execution. This vulnerability is exploitable remotely without any privileges or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). Successful exploitation can compromise confidentiality, integrity, and availability by allowing attackers to execute arbitrary code or cause denial of service. FFmpeg is embedded in numerous applications and services for video and audio processing, including streaming platforms, media players, and content delivery networks. The vulnerability is classified under CWE-415 (Double Free), a common and dangerous memory management flaw. Although no public exploits are currently reported, the critical severity and ease of exploitation necessitate urgent attention from users and vendors. No patches are currently linked, implying that mitigation may rely on upstream fixes or workarounds until official updates are released.

The impact on European organizations is substantial due to FFmpeg's extensive use in media processing across various industries such as broadcasting, telecommunications, and online streaming services. Exploitation could lead to remote code execution, allowing attackers to take control of affected systems, steal sensitive data, disrupt services, or pivot within networks. This poses a threat to confidentiality, integrity, and availability of critical multimedia infrastructure. Organizations handling large volumes of media content or providing media-related services are at heightened risk. The vulnerability could also affect embedded devices and IoT products using FFmpeg, potentially expanding the attack surface. Given the critical CVSS score and no requirement for authentication or user interaction, attackers could weaponize this flaw in automated attacks, increasing the likelihood of widespread exploitation. Disruptions could impact service availability and damage organizational reputation, especially in countries with advanced digital media ecosystems.

Until official patches are released, organizations should implement the following mitigations: 1) Restrict and validate all untrusted media inputs processed by FFmpeg to minimize exposure to crafted malicious files. 2) Employ application-level sandboxing or containerization to isolate FFmpeg processes and limit the impact of potential exploitation. 3) Monitor system and application logs for crashes or abnormal behavior related to media processing components. 4) Update intrusion detection and prevention systems with signatures targeting anomalous FFmpeg activity once available. 5) Engage with vendors and upstream FFmpeg maintainers to track patch releases and apply updates promptly. 6) For embedded systems, consider firmware updates or disabling vulnerable features if feasible. 7) Conduct internal audits to identify all FFmpeg usage within the organization to ensure comprehensive coverage of mitigation efforts. These steps go beyond generic advice by focusing on containment, input validation, and proactive monitoring tailored to this specific vulnerability.
