CVE-2006-0766: n/a vulnerability

CVE-2006-0766: ICQ Inc.

ICQ Inc. (formerly Mirabilis) ICQ 2003a, 2003b, Lite 4.0, Lite 4.1, and possibly other Windows versions allows user-assisted remote attackers to hide malicious file extensions and bypass Windows security warnings via a filename that ends in an assumed-safe extension such as JPG, and possibly containing other modified properties such as company name, icon, and description, which could trick a user into executing arbitrary programs.

Security readout for executives and security teams

This issue affects old Windows ICQ clients and can make a malicious program look like a safer file, such as an image. The attack still requires a user to run the file. Business urgency is mainly for organizations with legacy ICQ installations or archived unmanaged desktops. Exposure is likely limited to legacy Windows systems running ICQ 2003a, 2003b, Lite 4.0, Lite 4.1, or possibly similar-era ICQ Windows clients. Modern enterprise exposure is expected to be uncommon unless old software remains installed. Handle through legacy software hygiene rather than emergency response unless affected ICQ clients are present. If found on business systems, removal should be prioritized because the issue enables deceptive file execution and no source-provided patch details are available. Mitigation focus: Inventory Windows endpoints for legacy ICQ installations.; Remove or replace unsupported ICQ clients where found.; Check vendor or archived advisory guidance for any named update..
