The CPDF_DIBSource::CreateDecoder function in core/fpdfapi/fpdf_render/fpdf_render_loadimage.cpp in PDFium, as used in Google Chrome before 51.0.2704.63, mishandles decoder-initialization failure, 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

CVE-2016-1686 is a PDF handling flaw in PDFium used by Google Chrome before 51.0.2704.63. A malicious PDF could crash or disrupt the browser through an out-of-bounds read. The provided sources describe denial of service, not data theft or code execution. Primary exposure is legacy Google Chrome before 51.0.2704.63 and systems packaging affected Chromium/PDFium components per listed Linux vendor advisories. Modern, regularly updated browsers are unlikely to remain exposed, but embedded or pinned PDFium consumers need inventory confirmation. Treat this as a legacy hygiene issue unless old browser or PDF rendering stacks are still present. Business urgency rises for kiosks, VDI images, embedded products, or servers that process untrusted PDFs using outdated PDFium builds. Mitigation focus: Update Chrome to 51.0.2704.63 or later where applicable.; Apply relevant Debian, openSUSE, Red Hat, or Gentoo security updates.; Check vendor guidance for any embedded PDFium or Chromium-derived components..
