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
Ikarus Virus Utilities T3.1.1.45.0 and possibly T3.1.1.34.0, when Internet Explorer 6 or 7 is used, allows remote attackers to bypass detection of malware in an HTML document by placing an MZ header (aka "EXE info") at the beginning, and modifying the filename to have (1) no extension, (2) a .txt extension, or (3) a .jpg extension, as demonstrated by a document containing a CVE-2006-5745 exploit.

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

Ikarus Virus Utilities fails to detect malware in HTML documents when an MZ header (EXE marker) is placed at the beginning and the filename is given a no extension, .txt, or .jpg extension. This allows attackers to bypass antivirus detection of exploits like CVE-2006-5745 by manipulating file metadata rather than the malicious payload itself.

MitigationUsers should update to the latest version of Ikarus Virus Utilities or implement compensating controls such as disabling unnecessary file type associations and deploying additional email/web filtering. Since this is 2008-era software likely discontinued, consider migrating to actively maintained antivirus solutions.

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 Ikarus Antivirus is installed
    Check the system for Ikarus Antivirus installation. Look for Ikarus process (ikarus.exe or related service) in running processes, or check Program Files for Ikarus folder. Use: tasklist /FI "IMAGENAME eq ikarus*" on Windows or check installed programs list.
    Affected if Ikarus Antivirus is present on the system
  2. Identify installed Ikarus version
    Open Ikarus Antivirus and navigate to About/Help section to view version number. Alternatively, right-click ikarus.exe in the installation directory, select Properties, and check the Details tab for version information.
    Affected if Installed version matches t3.1.1.34.0 or t3.1.1.45.0 exactly
  3. Confirm antivirus real-time scanning is enabled
    Check Ikarus Antivirus settings to verify real-time file monitoring (on-access scanning) is active. Look for settings labeled 'Real-time protection', 'On-access scanning', or 'File monitor' in the antivirus control panel.
    Affected if Real-time scanning is enabled and version is affected
  4. Test file type handling for HTML with manipulated extensions
    Create a test file with no extension, .txt, or .jpg extension containing an MZ header (EXE marker) at the beginning. Attempt to scan this file with Ikarus Antivirus to see if it is detected or ignored.
    Affected if The antivirus fails to scan or detect malware in files matching these extension patterns (none, .txt, .jpg) when they contain executable headers

User is affected if Ikarus Antivirus version t3.1.1.34.0 or t3.1.1.45.0 is installed and real-time scanning is active, particularly when handling files with no extension, .txt, or .jpg extensions that contain MZ/EXE headers.
