PDFium in Google Chrome prior to 55.0.2883.75 for Mac, Windows and Linux, and 55.0.2883.84 for Android incorrectly handled navigation within PDFs, which allowed a remote attacker to read local files via a crafted PDF file.

Security readout for executives and security teams

This flaw affected Chrome’s built-in PDF viewer. A malicious PDF could make vulnerable Chrome versions read local files from the user’s device. The main business risk is data exposure from endpoints still running Chrome versions from before December 2016. Exposure is most likely limited to unmanaged, legacy, or unsupported devices still running affected Chrome versions. The source bundle names Google Chrome only; it does not establish impact for other PDFium consumers. Treat this as a legacy exposure cleanup item unless affected versions are still present. If old Chrome exists on endpoints handling sensitive files, prioritize removal because the impact is local file disclosure through routine PDF handling. Mitigation focus: Upgrade Chrome beyond the fixed versions named in the CVE.; Prefer current supported Chrome releases, not only the 2016 fixed baseline.; Retire or isolate endpoints unable to run supported browser versions..
