Out-of-Bounds read vulnerability in Foxit Reader and PhantomPDF before 8.1 on Windows, when the gflags app is enabled, allows remote attackers to execute arbitrary code via a crafted TIFF image embedded in the XFA stream in a PDF document, aka "Read Access Violation starting at FoxitReader."

Security readout for executives and security teams

This issue affects older Foxit Reader and PhantomPDF for Windows. A malicious PDF containing a crafted TIFF image inside an XFA stream could trigger memory access outside expected bounds and potentially run attacker-controlled code, but the source states this requires gflags to be enabled. Exposure is likely limited to Windows endpoints running Foxit Reader or PhantomPDF before 8.1, especially where gflags is enabled and users open untrusted PDFs. Current exposure depends on inventory; the bundled affected-product metadata is incomplete. Treat this as a targeted legacy endpoint risk. Prioritize remediation where old Foxit versions remain in use, especially on systems exposed to external PDFs. The business urgency is lower if inventory confirms no pre-8.1 Foxit deployments or no gflags-enabled systems. Mitigation focus: Identify Foxit Reader and PhantomPDF installations older than 8.1 on Windows.; Upgrade affected Foxit products to 8.1 or later per Foxit guidance.; Review whether gflags is enabled on user workstations and remove unnecessary debugging configuration..
