Heap-based buffer overflow in the opj_j2k_read_SPCod_SPCoc function in j2k.c in OpenJPEG, as used in PDFium in Google Chrome before 51.0.2704.63, allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted PDF document.

Security readout for executives and security teams

CVE-2016-1681 is a memory corruption issue in OpenJPEG as used by Chrome PDFium. A crafted PDF could crash the browser and may have had other unspecified impact. The known Chrome fix shipped before version 51.0.2704.63. No provided source confirms active exploitation. Exposure is most plausible in legacy Google Chrome or Chromium/PDFium deployments older than 51.0.2704.63, and Linux distribution packages covered by the cited 2016 vendor advisories. Current managed browsers are unlikely exposed if regularly updated. Treat this as a legacy exposure cleanup item unless old browser or PDF rendering stacks remain in use. Prioritize environments processing untrusted PDFs, kiosks, VDI images, and unmanaged endpoints with outdated software. Mitigation focus: Upgrade Chrome or Chromium-derived PDFium builds beyond 51.0.2704.63.; Apply relevant Debian, Red Hat, Gentoo, or openSUSE security updates where applicable.; Review vendor advisories for affected package names and supported fixed versions..
