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
Konqueror 3.5.5 allows remote attackers to cause a denial of service (crash) by using JavaScript to read a child iframe having an ftp:// URI.

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

Konqueror 3.5.5 contains a flaw where JavaScript code can trigger a crash by reading a child iframe element that contains an ftp:// URI, causing a denial of service.

MitigationUpgrade Konqueror to a version newer than 3.5.5 that includes the fix for this vulnerability, or apply any available security patches from KDE for this issue.

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 Konqueror is installed
    Run 'which konqueror' or 'konqueror --version' to locate the binary
    Affected if Konqueror is not found on the system
  2. Determine installed Konqueror version
    Run 'konqueror --version' and parse the version number from the output
    Affected if Version is exactly 3.5.5
  3. Check if JavaScript is enabled
    Inspect Konqueror settings via configuration files in ~/.kde/ or ~/.config/kde.org/ or check via Konqueror's JavaScript settings interface
    Affected if JavaScript is enabled - the exploit requires JavaScript execution to trigger the crash when accessing an ftp:// iframe

You are affected if Konqueror version 3.5.5 is installed and JavaScript is enabled, allowing a malicious webpage with JavaScript that reads an ftp:// iframe to crash the browser.
