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 installed JustSystems productsCheck Windows Program Files for JustSystems folders (JustSystems, Ichitaro, Shuriken, or similar naming), or review installed programs list for JustSystems software titlesAffected if Any JustSystems product from the affected product list is present
-
Determine Ichitaro versionOpen Ichitaro, go to Help > About, or check the executable properties (ichitaro.exe) file version metadataAffected if Version equals 2006, 2007, 2008, 2009, 2010, or 2011
-
Check for oreplug pluginLook for oreplug.dll in the Ichitaro program directory, or check Ichitaro plugin/add-in settings under Tools > Options > Plugin or Add-in managementAffected if Oreplug plugin is loaded or present in the installation
-
Identify other affected JustSystems softwareCheck installed programs for Just Frontier, Just Jump (version 4), Just School (all versions or 2009/2010), or Rekishimail Bakumatsushishi No MisshoAffected if Any of these products are installed
-
Verify image file handling capabilityConfirm the product can open or process image files (check file association settings or supported file types in the application)Affected if The product has active image file parsing functionality enabled
Your environment is affected if any JustSystems Ichitaro version 2006-2011, any version of Ichitaro with oreplug, Ichitaro Viewer, Just Frontier, Just School, or other listed products are installed with image file processing capability enabled.

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 dataAvoid opening untrusted or unexpected image files in affected JustSystems products. Apply vendor patches when available. Consider disabling the oreplug plugin if not required for business functions.
