CVE-2018-19346
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe u3d plugin 9.3.0.10809 (aka plugins\U3DBrowser.fpi) in FoxitReader.exe in Foxit Reader 9.3.0.10826 allows remote attackers to cause a denial of service (out-of-bounds read) or obtain sensitive information via a U3D sample because of a "Data from Faulting Address controls Branch Selection starting at U3DBrowser!PlugInMain+0x00000000000d11ea" issue.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceFoxit Reader 9.3.0.10826 contains a vulnerable version of the U3DBrowser.fpi plugin (9.3.0.10809) that suffers from an out-of-bounds read vulnerability when processing specially crafted U3D (Universal 3D) sample files. The vulnerability allows remote attackers to cause a denial of service or potentially obtain sensitive information by controlling data at a faulting address that influences branch selection logic.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Foxit Reader versionCheck the installed Foxit Reader version via Help > About or by examining the executable properties (FoxitReader.exe) in the installation directory. Typical paths: C:\Program Files\Foxit Software\Foxit Reader\ or C:\Program Files (x86)\Foxit Software\Foxit Reader\Affected if The installed version is exactly 9.3.0.10826
-
Locate and verify U3DBrowser.fpi plugin versionNavigate to the Plugins folder within the Foxit Reader installation directory (for example: C:\Program Files\Foxit Software\Foxit Reader\Plugins\). Locate the U3DBrowser.fpi file, right-click and view Properties > Details to confirm the file version.Affected if The U3DBrowser.fpi plugin version is 9.3.0.10809
-
Confirm U3D plugin is enabledOpen Foxit Reader, go to File > Preferences > Security > Trust Manager, or check the Plugins Manager (Home > Protect > Security Settings > Plugins). Verify whether U3DBrowser is listed as enabled/loaded.Affected if The U3DBrowser plugin is enabled and loaded by Foxit Reader
-
Check if U3D file handling is activeAttempt to open a .u3d file or verify file associations. U3D files are often used in PDF documents for 3D content. Check if the application can process 3D content within PDF files.Affected if U3D file processing or 3D content rendering is enabled and functional in Foxit Reader
All four conditions must be true for the system to be affected: Foxit Reader 9.3.0.10826 is installed, U3DBrowser.fpi version 9.3.0.10809 is present, the U3D plugin is enabled, and the application can process U3D/3D content.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-supplied patches from Foxit Reader to update the U3D plugin to a non-vulnerable version, and consider disabling the U3D plugin if not required for business functions.
