The MP4_ReadBox_String function in modules/demux/mp4/libmp4.c in VideoLAN VLC media player before 2.1.6 performs an incorrect cast operation from a 64-bit integer to a 32-bit integer, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a large box size.

Security readout for executives and security teams

CVE-2014-9627 affects VLC media player before 2.1.6 when parsing MP4 metadata. A specially crafted MP4 with an oversized box can crash VLC, causing denial of service. The sources also mention possible unspecified impact, but provide no confirmed details beyond that. Exposure is most likely on endpoints, kiosks, media review systems, or applications using vulnerable VLC versions before 2.1.6 to open MP4 files. The bundle does not provide CPEs or a complete affected platform list, so inventory validation is necessary. Prioritize remediation where users or automated workflows open external MP4 files. Business risk is mainly disruption from crashes, with incomplete evidence for broader impact. This should be addressed in normal patch cycles unless VLC is used in exposed media intake workflows. Mitigation focus: Upgrade VLC media player to version 2.1.6 or later.; Review VideoLAN SA1501 for vendor-confirmed remediation details.; Restrict opening untrusted MP4 files on systems still running vulnerable VLC..
