CVE-2022-43035: n/a in n/a
An issue was discovered in Bento4 v1.6.0-639. There is a heap-buffer-overflow in AP4_Dec3Atom::AP4_Dec3Atom at Ap4Dec3Atom.cpp, leading to a Denial of Service (DoS), as demonstrated by mp42aac.
AI Analysis
Technical Summary
CVE-2022-43035 is a medium severity vulnerability identified in Bento4 version 1.6.0-639, specifically involving a heap-based buffer overflow in the AP4_Dec3Atom constructor within the Ap4Dec3Atom.cpp source file. Bento4 is an open-source multimedia framework widely used for parsing, processing, and packaging MP4 files. The vulnerability arises when processing certain crafted MP4 files, as demonstrated by the mp42aac tool, which triggers the heap-buffer-overflow condition. This overflow can lead to a Denial of Service (DoS) by crashing the application or causing it to behave unpredictably. The vulnerability is classified under CWE-787 (Out-of-bounds Write), indicating that the software writes data outside the bounds of allocated memory buffers. The CVSS v3.1 base score is 6.5, reflecting a medium severity level, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The impact is limited to availability (A:H), with no confidentiality or integrity impact. No known exploits are currently reported in the wild, and no patches or vendor advisories are linked, suggesting that mitigation may require manual updates or workarounds. The vulnerability could be triggered by processing malicious MP4 files, potentially causing applications or services relying on Bento4 to crash or become unresponsive, impacting media processing pipelines or user applications that handle MP4 content.
Potential Impact
For European organizations, the impact of CVE-2022-43035 primarily involves service disruption due to Denial of Service conditions in applications or services that utilize Bento4 for MP4 file handling. This can affect media companies, broadcasters, streaming services, and any enterprise relying on automated media processing workflows. Disruptions could lead to downtime, degraded user experience, or interruption of media delivery services. While the vulnerability does not compromise confidentiality or integrity, the availability impact can affect business continuity, especially for organizations with high reliance on multimedia content processing. Additionally, if exploited in client-facing applications, it could be used as a vector for targeted DoS attacks by sending crafted MP4 files to users or services. Given the lack of known exploits, the immediate risk is moderate, but organizations should remain vigilant, especially those in sectors like media, telecommunications, and content distribution within Europe.
Mitigation Recommendations
To mitigate CVE-2022-43035, European organizations should: 1) Identify and inventory all systems and applications using Bento4, particularly version 1.6.0-639 or earlier. 2) Monitor vendor channels and Bento4 repositories for patches or updates addressing this vulnerability and apply them promptly once available. 3) Implement input validation and sanitization controls to detect and block malformed or suspicious MP4 files before processing. 4) Employ sandboxing or isolation techniques for media processing components to contain potential crashes and prevent wider system impact. 5) Use application-level monitoring and alerting to detect abnormal crashes or service disruptions related to media processing. 6) Educate users and administrators about the risks of opening or processing untrusted MP4 files, especially from external or unknown sources. 7) Consider deploying network-level protections such as file scanning and filtering to intercept malicious media files. These targeted measures go beyond generic advice by focusing on the specific context of Bento4 usage and media file handling.
