The sycc422_to_rgb function in fxcodec/codec/fx_codec_jpx_opj.cpp in PDFium, as used in Google Chrome before 40.0.2214.91, does not properly handle odd values of image width, which allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted PDF document.

Security readout for executives and security teams

A crafted PDF could crash affected Chrome/PDFium PDF rendering because an image conversion routine mishandles odd image widths. The documented impact is denial of service, not data theft or remote code execution. The issue is old and was fixed in Chrome 40.0.2214.91, but legacy embedded PDFium deployments may still matter. Exposure is most likely in obsolete Chrome builds, old Chromium-derived packages, or products embedding vulnerable PDFium code. Modern managed Chrome deployments are unlikely to remain exposed, but unsupported appliances or bundled PDF viewers should be checked. Treat this as a legacy hygiene issue unless old browsers or embedded PDF viewers are still present. Business urgency rises where untrusted PDFs are opened on unsupported systems or where PDF rendering crashes would disrupt operations. Mitigation focus: Upgrade Google Chrome to 40.0.2214.91 or later.; Patch Chromium/PDFium packages using relevant Linux vendor advisories.; Identify applications that bundle PDFium and confirm their PDFium fix level..
