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
Format string vulnerability in the embedded Internet Explorer component for Mirabilis ICQ 6 build 6043 allows remote servers to execute arbitrary code or cause a denial of service (crash) via unspecified vectors related to HTML code generation.

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

Format string vulnerability in the embedded Internet Explorer component of Mirabilis ICQ 6 build 6043 allows remote servers to inject arbitrary format specifiers into HTML code generation, potentially leading to stack corruption and arbitrary code execution, or denial of service via crash.

MitigationSince ICQ 6 is a discontinued legacy product with no official patch likely available, migrate to a supported ICQ client version or alternative messaging platform; as an interim control, restrict network connectivity to trusted servers and disable embedded browser components if possible.

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 ICQ 6 is installed
    Check for ICQ installation directory (typically C:\Program Files\ICQ6 or C:\Program Files\Mirabilis\ICQ) or look in Windows Registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for ICQ entries
    Affected if ICQ version 6.x is present on the system
  2. Confirm exact ICQ version
    Right-click the ICQ executable (icq.exe) in the installation folder, select Properties, and check the File Version field; alternatively, open ICQ and go to Help > About to view the build number
    Affected if Version displays as 6.x with build 6043 or any 6.x release
  3. Verify embedded Internet Explorer component is active
    ICQ 6 uses an embedded IE rendering engine for HTML messages, banner ads, and web content within the client; check if ICQ can display HTML content in message windows or if the internal browser is functional
    Affected if The embedded browser component is enabled and functional (default state in ICQ 6)
  4. Assess network exposure
    ICQ connects to ICQ servers for messaging; check if the client has active network connections to ICQ servers or if firewall rules permit ICQ traffic
    Affected if Network connectivity to ICQ servers is allowed and the client can receive HTML content from remote servers

A user is affected if ICQ version 6 is installed with the embedded browser component enabled and the system has network access to ICQ servers, allowing remote format string injection into HTML rendering.
