An issue in Bento4 v1.6.0-641 allows an attacker to cause a memory leak via Ap4Marlin.cpp and Ap4Processor.cpp, specifically in AP4_MarlinIpmpEncryptingProcessor::Initialize and AP4_Processor::Process, during the execution of mp4encrypt with a specially crafted MP4 input file. This vulnerability carries a CVSS score of 5.5, classifying it as medium severity. The vulnerability is significant because it could lead to a high availability impact, potentially leading to system instability or crashes.
The attack vector is local, requiring user interaction to exploit the vulnerability. Attackers may leverage this weakness to disrupt service availability, which could have serious implications for organizations relying on the affected software.
Given the potential impact on system availability, organizations should prioritize reviewing and patching their Bento4 installations. The vulnerability was published on February 19, 2025, and remains under analysis as of the latest modification date, June 9, 2025.
Organizations should assess the risk this vulnerability poses to their operations. With the memory leak issue, systems may become more susceptible to denial-of-service attacks if not addressed promptly.
Vulnerability Details
The vulnerability in Bento4 affects the processing of MP4 files, specifically through the functions AP4_MarlinIpmpEncryptingProcessor::Initialize and AP4_Processor::Process. The official CVE description states: "An issue in Bento4 v1.6.0-641 allows an attacker to cause a memory leak via Ap4Marlin.cpp and Ap4Processor.cpp, specifically in AP4_MarlinIpmpEncryptingProcessor::Initialize and AP4_Processor::Process, during the execution of mp4encrypt with a specially crafted MP4 input file."
The CVSS score of 5.5 indicates a medium severity, with the following vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H. The attack complexity is low, and no privileges are required for exploitation, which highlights the ease with which an attacker could initiate an exploit.
Technical Analysis
The root cause of this vulnerability stems from improper handling of memory within the Bento4 software during the processing of specially crafted MP4 files. The attack vector is classified as local, meaning that an attacker must have access to the system to exploit this vulnerability.
The attack complexity is low, as the attacker does not require special privileges and only minimal user interaction is necessary. This could include simply opening a malicious MP4 file. The availability impact is high, as the memory leak may lead to application crashes or instability, potentially taking the service offline.
In terms of confidentiality and integrity, there is no impact, as this vulnerability does not compromise sensitive data or alter system functionalities. It strictly affects the system's availability.
Risk & Impact Analysis
Risk to organizations includes potential downtime and service disruption due to the memory leak vulnerability. If exploited, this could lead to significant operational challenges, especially for services that rely on the Bento4 processing capabilities.
The blast radius for this vulnerability is moderate, potentially impacting all users of the affected version of Bento4. Organizations should assess their exposure and determine the urgency of remediation based on their specific usage of the software.
Given the CVSS score of 5.5, organizations should address this vulnerability in their priority patch cycle. Although not classified as critical, the potential for high availability impact necessitates prompt action.
