CVE-2024-41206 is a stack-based buffer over-read vulnerability identified in the tsMuxer software, specifically in the nightly build dated 2024-03-14. tsMuxer is a tool used for multiplexing video streams, including Transport Stream (TS) files. The vulnerability arises when tsMuxer processes a crafted TS video file, leading to reading beyond the allocated stack buffer boundaries. This over-read can leak sensitive information from the process memory, resulting in an information disclosure vulnerability. The vulnerability does not allow code execution or denial of service but compromises confidentiality by exposing potentially sensitive data in memory. The CVSS 3.1 base score is 6.5 (medium), with an attack vector of network (remote attacker), low attack complexity, no privileges required, but user interaction is necessary (opening the malicious file). The scope is unchanged, and the impact is high on confidentiality but none on integrity or availability. This vulnerability is categorized under CWE-120, a common weakness related to buffer over-read errors. Currently, there are no known exploits in the wild, and no official patches have been released. The vulnerability affects the nightly build version of tsMuxer, and it is unclear if stable releases are impacted. Users of tsMuxer should be aware of this risk when handling untrusted TS files.

The primary impact of CVE-2024-41206 is the unauthorized disclosure of information from the memory space of the tsMuxer process. This could include sensitive data such as cryptographic keys, user data, or other confidential information residing in memory at the time of exploitation. For organizations involved in media processing, broadcasting, or video content creation using tsMuxer, this could lead to leakage of proprietary or sensitive content. Although the vulnerability does not allow attackers to execute arbitrary code or cause denial of service, the confidentiality breach could facilitate further attacks or data leaks. Since exploitation requires user interaction (opening a crafted TS file), the risk is somewhat mitigated by user awareness but remains significant in environments where untrusted media files are processed. The lack of patches increases exposure duration. Overall, the vulnerability could undermine trust in media processing workflows and potentially expose sensitive operational data.

1. Avoid processing untrusted or unauthenticated TS video files with tsMuxer, especially the affected nightly builds. 2. Monitor the official tsMuxer project repositories and security advisories for patches or updates addressing CVE-2024-41206 and apply them promptly once available. 3. Implement strict input validation and sandboxing around media processing tools to limit the impact of malformed files. 4. Employ endpoint protection solutions that can detect anomalous behavior during media file processing. 5. Educate users and operators about the risks of opening untrusted media files and enforce policies restricting such actions. 6. Consider using alternative, vetted media multiplexing tools with a strong security track record until a patch is released. 7. Use memory protection mechanisms and compiler-based mitigations (e.g., stack canaries, ASLR) to reduce the risk of buffer over-read exploitation. 8. Conduct regular security assessments of media processing pipelines to identify and remediate similar vulnerabilities proactively.
