An issue in Bento4 v1.6.0-641 allows an attacker to trigger a segmentation fault via Ap4Atom.cpp, specifically in AP4_AtomParent::RemoveChild, during the execution of mp4encrypt with a specially crafted MP4 input file. This vulnerability has a CVSS score of 5.5, categorizing it as medium severity. The implications of this vulnerability can impact the availability of the affected system, making it crucial for organizations to address it promptly.
The vulnerability was published on February 19, 2025, and organizations should prioritize reviewing their use of Bento4 to mitigate potential risks. While no public exploits are confirmed and it is not included in the Known Exploited Vulnerabilities (KEV) catalog, organizations should still implement remediation measures as part of their security posture.
Risk to organizations includes potential service disruptions due to segmentation faults triggered by maliciously crafted MP4 files. To minimize risk, organizations should ensure they are using up-to-date versions of affected software and consider implementing additional monitoring and logging for unusual activities related to media file processing.
Urgency for defenders is medium, and organizations should address this vulnerability in their priority patch cycle. Regular reviews and security assessments can help identify and mitigate such vulnerabilities before they can be exploited.
Vulnerability Details
The vulnerability in question relates to Bento4 version 1.6.0-641 and is classified as CWE-665. The CVSS base score of 5.5 indicates a medium severity level, which reflects the potential for high availability impact while confidentiality and integrity impacts are rated as none. This vulnerability highlights the importance of robust input validation mechanisms in software handling media files.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of input data, specifically in the AP4_AtomParent::RemoveChild function, which leads to a segmentation fault when mp4encrypt processes maliciously crafted MP4 files. The attack vector is local, with low complexity and no privileges required. However, user interaction is necessary for an attacker to exploit this vulnerability, as the target must run the mp4encrypt command with the manipulated file.
The attack complexity is low, indicating that the vulnerability can be exploited without advanced skills. The availability impact is high, as a successful exploit will result in a crash of the application processing the MP4 file. Organizations should be aware of the need for user awareness regarding file handling practices.
Risk & Impact Analysis
The real-world risk associated with this vulnerability is significant, particularly for organizations that rely on Bento4 for media processing. The potential for service disruption due to application crashes could lead to operational inefficiencies and loss of availability. Furthermore, if exploited, this vulnerability could serve as a stepping stone for further attacks within an organization's infrastructure.
Organizations must evaluate the urgency of addressing this vulnerability within the context of their overall risk management strategy. Given the medium CVSS score and the potential availability impact, organizations should consider this a priority in their patch management process.
