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
Buffer overflow in the XML parser of Trillian 0.6351, 0.725 and 0.73 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a skin with a long colors file name in trillian.xml.

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

Buffer overflow vulnerability in Trillian's XML parser allows remote attackers to cause denial of service and potentially execute arbitrary code via a skin file (trillian.xml) containing an excessively long colors filename. The vulnerability exists in versions 0.6351, 0.725, and 0.73 of the Trillian instant messaging client.

MitigationTrillian versions 0.73 and earlier from 2002 are no longer supported; users should migrate to current Trillian versions or use alternative instant messaging platforms, as no patch is available for these legacy versions.

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 Trillian installation
    Check for Trillian installation directory (typically C:\Program Files\Trillian or C:\Program Files (x86)\Trillian) and verify the executable exists
    Affected if Trillian is installed on the system
  2. Determine installed Trillian version
    Right-click trillian.exe, select Properties, and check the Version tab for the product version; or launch Trillian and go to Help > About Trillian
    Affected if Version displayed is 0.6351, 0.725, or 0.73 exactly
  3. Confirm skin functionality is in use
    Check for the presence of trillian.xml skin file in the users AppData\Roaming\Trillian\skins folder or the program's skins directory
    Affected if Skin files are present and skins feature is enabled (default behavior)
  4. Identify vulnerable XML parser configuration
    Examine the trillian.xml skin file for the colors filename entry; look for unusually long filename strings in the colors or themes section
    Affected if Colors filename value exceeds normal length (typical values are under 100 characters)

User is affected if Trillian versions 0.6351, 0.725, or 0.73 are installed with skins functionality enabled and a trillian.xml skin file containing an excessively long colors filename is present.
