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
IrfanView 4.50 - 64bit with CADImage plugin version 12.0.0.5 allows attackers to cause a denial of service or possibly have unspecified other impact via a crafted .dwg file, related to "Data from Faulting Address may be used as a return value starting at CADIMAGE+0x00000000003d24a0."

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 confidence

A memory corruption vulnerability exists in IrfanView 4.50 64-bit with CADImage plugin version 12.0.0.5 when parsing crafted .dwg files. The vulnerability occurs because data from a faulting address is used as a return value (CADIMAGE+0x00000000003d24a0), indicating a type confusion or out-of-bounds read issue that can cause denial of service or potentially other unspecified impacts.

MitigationAvoid opening untrusted or unverified .dwg files in IrfanView with the CADImage plugin. Update the CADImage plugin to a patched version if available, or disable/remove the plugin until an update can be applied.

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. Identify installed IrfanView version
    Locate the IrfanView executable (typically in Program Files) and check its version property, or use system inventory tools to query the installed version
    Affected if The installed version is exactly 4.50 (64-bit)
  2. Locate and identify CADImage plugin version
    Find the CADImage plugin DLL file (commonly cadimage.dll) within the IrfanView plugins directory and check its file version property
    Affected if The CADImage plugin version is 12.0.0.5
  3. Confirm both conditions are true simultaneously
    Verify that IrfanView 4.50 and CADImage plugin 12.0.0.5 are both present on the same system
    Affected if Both IrfanView 4.50 and CADImage plugin 12.0.0.5 are installed together
  4. Check if CADImage plugin is loaded or enabled
    Attempt to open a .dwg file in IrfanView or check plugin loading status, or examine if the plugin DLL is being actively loaded by IrfanView
    Affected if The CADImage plugin can process .dwg files through IrfanView

A system is affected if it runs IrfanView 4.50 with the CADImage plugin version 12.0.0.5 and that plugin is capable of opening .dwg files.
