CVE-2020-16232
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 · uneditedIn Yokogawa WideField3 R1.01 - R4.03, a buffer overflow could be caused when a user loads a maliciously crafted project file.
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 confidenceA buffer overflow vulnerability exists in Yokogawa WideField3 versions R1.01 through R4.03. The vulnerability is triggered when a user opens a maliciously crafted project file, potentially allowing an attacker to execute arbitrary code due to improper bounds checking when parsing file contents.

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 Yokogawa WideField3 is installedCheck program files for the WideField3 directory, or look for WideField3 in the system list of installed applicationsAffected if WideField3 software is present on the system
-
Determine the installed WideField3 versionOpen WideField3 and navigate to Help > About, or locate the version info in the installation directoryAffected if The displayed version falls within R1.01 through R4.03 (inclusive)
-
Confirm the software handles project filesVerify that WideField3 is used to open or import project files with extensions such as .wfp or similarAffected if The software processes project files, making the file parsing vulnerable to the buffer overflow
-
Check for recent file access from untrusted sourcesReview recent project files opened in WideField3, particularly files from email attachments, external drives, or untrusted network locationsAffected if Any project file from an untrusted or unknown source was opened in the affected version range
A user is affected if Yokogawa WideField3 version R1.01 through R4.03 is installed and the software is used to open project files, especially those from untrusted sources.

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 for WideField3 R4.04 or later. Until patches are applied, exercise extreme caution with project files from untrusted sources and consider network segmentation to limit exposure.
