CVE-2018-17930
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 · uneditedA stack-based buffer overflow vulnerability has been identified in Teledyne DALSA Sherlock Version 7.2.7.4 and prior, which may allow remote code execution.
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 confidenceA stack-based buffer overflow vulnerability exists in Teledyne DALSA Sherlock machine vision software versions 7.2.7.4 and prior. The overflow occurs when the application processes input data, allowing an attacker to overwrite stack memory and potentially execute arbitrary code remotely.

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 the installed Teledyne DALSA Sherlock versionLocate and inspect the Sherlock installation directory or use the software's built-in About/Version information dialog. Common locations include C:\Program Files\Teledyne DALSA\Sherlock or the application's help menu.Affected if The installed version number is 7.2.7.4 or any earlier version (for example, 7.2.7.3, 7.2.6.0, etc.)
-
Check the exact version string in installed binariesIf the software is installed, locate the main executable (typically named Sherlock.exe or similar) and view its file properties to confirm the Product Version field.Affected if The Product Version field shows a version equal to or lower than 7.2.7.4
-
Verify network exposure of the Sherlock serviceReview network configuration, firewall rules, or service binding settings to determine if the Sherlock application or its processing services are accessible over the network.Affected if The Sherlock service is bound to a network-accessible IP address or interface and accepts remote connections
-
Confirm the application handles external input dataExamine Sherlock project configurations, recipe files, or automation scripts to determine if the software processes input data from external sources such as files, network streams, or automated workflows.Affected if The software is configured to accept or process input data from external sources, network feeds, or automated recipe loading
You are affected if Teledyne DALSA Sherlock version 7.2.7.4 or earlier is installed and the application processes external input data or is network-accessible.

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 dataUpgrade Teledyne DALSA Sherlock to a version newer than 7.2.7.4. If immediate patching is not possible, restrict network access to the Sherlock service and implement input validation controls at network boundaries.
