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 · uneditedInterScan VirusWall SMTP scanner does not properly scan messages with malformed attachments.
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 · moderate confidenceInterScan VirusWall SMTP scanner fails to properly scan email messages with malformed attachments, potentially allowing viruses and malware to bypass detection and enter the network through email. The scanner likely crashes, times out, or skips processing when encountering malformed MIME structures or attachment headers.

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.
-
Identify if Trend Micro InterScan VirusWall is installedCheck for the presence of InterScan VirusWall on the system by looking for its installation directory, service, or executable. Common locations include C:\Program Files\Trend Micro\Interscan Viruswall or /opt/TrendMicro/VirusWall. On Windows, check the Services control panel for 'InterScan VirusWall' service.Affected if The software is present on the system
-
Verify the installed version numberLocate the version information for InterScan VirusWall. This is typically found in the program's about dialog, in a version file within the installation directory, or via the command line if a version flag is supported (such as iscan --version or similar). Compare the installed version to the affected version 3.0.1.Affected if The installed version is exactly 3.0.1
-
Confirm SMTP scanning module is enabledCheck the InterScan VirusWall configuration to determine if the SMTP scanner component is active. This is typically configured through the VirusWall console or configuration files (often named vsapi.ini, SmtpScan.cfg, or similar in the installation directory).Affected if SMTP scanning is enabled and the version is 3.0.1
-
Verify the SMTP service is runningConfirm that the InterScan VirusWall SMTP scanner service or daemon is currently running and accepting connections. On Windows, check the service status in Services. On Unix, check with commands like ps aux | grep iscan or similar.Affected if The SMTP scanner service is running and the version is 3.0.1
A system is affected only if Trend Micro InterScan VirusWall version 3.0.1 is installed with the SMTP scanning module enabled and operational.

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 dataVerify the installed version of InterScan VirusWall and apply any available patches. Consider implementing secondary email security controls such as additional gateway scanning, attachment sandboxing, or email filtering to compensate for detection gaps.
