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 version 4.44 (32bit) with PDF plugin version 4.43 allows attackers to cause a denial of service or possibly have unspecified other impact via a crafted .pdf file, related to "Data from Faulting Address controls Branch Selection starting at PDF!xmlParserInputRead+0x000000000011624a."

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 vulnerability in IrfanView PDF plugin version 4.43 allows attackers to cause denial of service or potentially achieve code execution via a crafted .pdf file. The vulnerability involves memory corruption at the xmlParserInputRead function where data from a faulting address controls branch selection, indicating a control-flow hijack condition.

MitigationAvoid opening untrusted or unknown PDF files in IrfanView until the PDF plugin is updated to a patched version. Verify current IrfanView and PDF plugin versions across the environment and apply available updates.

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. Confirm IrfanView is installed
    Check for IrfanView installation directory (typically C:\Program Files\IrfanView or C:\Program Files (x86)\IrfanView) and verify the main IrfanView executable (i_view32.exe or i_view64.exe) exists.
    Affected if IrfanView executable is present on the system
  2. Locate the PDF plugin
    Navigate to the IrfanView plugins subdirectory and look for the PDF plugin file (commonly named Pdf.dll or similar PDF-related DLL).
    Affected if PDF plugin file exists in the plugins folder
  3. Identify the PDF plugin version
    Right-click the PDF plugin DLL, select Properties, then view the Details tab to find the File Version. Alternatively, use a tool like PowerShell: (Get-Item 'C:\Program Files\IrfanView\Plugins\Pdf.dll').VersionInfo.FileVersion
    Affected if PDF plugin version is 4.43 or if version cannot be determined but the plugin is present
  4. Verify IrfanView version if known
    Right-click the IrfanView executable (i_view32.exe or i_view64.exe), select Properties, and check the File Version in the Details tab.
    Affected if IrfanView version is 4.44 with the vulnerable PDF plugin present
  5. Confirm PDF plugin is enabled
    Open IrfanView, go to menu: Options > Properties/Settings > Plug-ins. Verify the PDF plugin is listed as loaded/enabled.
    Affected if PDF plugin is loaded and active in IrfanView

The system is affected if IrfanView with the PDF plugin (versions 4.43 or 4.44) is installed and the PDF plugin is enabled, allowing crafted PDF files to trigger the memory corruption vulnerability.
