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 · unedited
There is a memory corruption vulnerability due to an out of bounds read in Bitmap::InternalDraw() when using the SymbolEditor in NI Circuit Design Suite.  This vulnerability may result in information disclosure or arbitrary code execution. Successful exploitation requires an attacker to get a user to open a specially crafted .sym file. This vulnerability affects NI Circuit Design Suite 14.3.0 and prior versions.

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 confidence

An out-of-bounds read vulnerability exists in Bitmap::InternalDraw() within NI Circuit Design Suite's SymbolEditor component. The vulnerability is triggered when parsing specially crafted .sym files containing malicious bitmap data, leading to memory corruption that can result in information disclosure or arbitrary code execution.

MitigationUsers should avoid opening .sym files from untrusted sources. Organizations should update to a patched version of NI Circuit Design Suite once available, or implement file sanitization/validation policies for .sym files.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify NI Circuit Design Suite installation
    Check the installed programs list in Windows Control Panel or use 'Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion' in PowerShell to list installed software and versions
    Affected if NI Circuit Design Suite appears in the installed programs list
  2. Confirm the installed version number
    Locate the version of NI Circuit Design Suite from the program list or check the program's About/Help section; compare the version number against 14.3.1
    Affected if The installed version is below 14.3.1 (for example, 14.0, 14.1, 14.2, or any version prior to 14.3.1)
  3. Identify SymbolEditor component usage
    Check if the SymbolEditor component is accessible by looking for SymbolEditor.exe or related .sym file handling functionality within the NI Circuit Design Suite installation directory
    Affected if SymbolEditor component is present and functional within the installed version
  4. Determine exposure to .sym file parsing
    Review whether users in the environment have the ability to open or import .sym files through the SymbolEditor; check for recent .sym file access logs or user workflows involving .sym files
    Affected if Users can or do open .sym files using the SymbolEditor component

A user is affected if NI Circuit Design Suite is installed with a version lower than 14.3.1 and the SymbolEditor component is used to open .sym files.

Upgrade available Upgrade to 14.3.1 or later
Fixed in 14.3.1
Interim mitigation

Users should avoid opening .sym files from untrusted sources. Organizations should update to a patched version of NI Circuit Design Suite once available, or implement file sanitization/validation policies for .sym files.

Recommended fix High confidence

NI Circuit Design Suite 14.3.1

  1. 1. Close any running instances of NI Circuit Design Suite
  2. 2. Back up any existing projects and custom symbol files (.sym)
  3. 3. Download NI Circuit Design Suite version 14.3.1 or later from the official NI website (www.ni.com)
  4. 4. Run the installer with administrator privileges
  5. 5. Follow the installation wizard prompts to complete the upgrade
  6. 6. After installation, verify the installed version matches 14.3.1 or later
  7. 7. Do not open any untrusted .sym files received from external sources
