The cdf_check_stream_offset function in cdf.c in file before 5.19, as used in the Fileinfo component in PHP before 5.4.30 and 5.5.x before 5.5.14, relies on incorrect sector-size data, which allows remote attackers to cause a denial of service (application crash) via a crafted stream offset in a CDF file.

Security readout for executives and security teams

This flaw can crash software that inspects certain document files. A remote attacker could send or upload a crafted CDF file and trigger a denial of service where vulnerable file identification code is used, including PHP Fileinfo in older PHP releases. Exposure is most likely in systems that process untrusted files with libmagic/file or PHP Fileinfo, such as upload validation, attachment scanning, or content-type detection. The source bundle does not identify specific deployed applications beyond file and PHP Fileinfo versions. Treat this as a targeted availability risk, not a confirmed breach indicator. Prioritize internet-facing upload or mail-processing services, especially legacy PHP stacks, then remediate through normal patch management. Mitigation focus: Upgrade file/libmagic to version 5.19 or a vendor-patched package.; Upgrade PHP to 5.4.30, 5.5.14, or a supported vendor-fixed release.; Apply relevant OS vendor advisories from Debian, Red Hat, Apple, Oracle, or HP..
