Microsoft Shortcut (LNK) Vulnerability
(MS10-046, 2286198, CVE-2010-2568)

A critical zero-day .LNK (shortcut) vulnerability in Microsoft Windows that is being actively exploited in the wild by the “Stuxnet” worm and “Sality” malware family has prompted Microsoft to issue an emergency patch 17 days after public disclosure of the vulnerability. However, the update did not patch Windows XP SP2 or Windows 2000, since those operating systems have reached end-of-support. The Check Point IPS Software Blade, IPS-1 and NGX SmartDefense provide immediate network protection for all versions of Windows in the latest IPS Update by detecting and blocking the transferring of suspicious .LNK files over CIFS.

A critical remote code execution vulnerability has been reported in the Microsoft DirectShow MP3 filter. Successful exploitation of this issue may allow the attacker take complete control of an affected system by convincing a victim to open a specially crafted MP3 file.

Deployment Tip
Best Practice:  Configuring automatic IPS contract updates to work through a proxy server
Check Point Security Management is designed to fit into complex customer environments, and provide easy-to-use centralized management. For example, it’s a simple process to enable proxied connections for IPS contract updates from the Security Management server. To do this, use the same procedure as you would for proxy configuration of IPS updates.
  1. In the SmartDashboard application, go to IPS--> Download Updates
  2. Choose the “Configure” near the proxy settings
  3. Configure the proxy settings as desired.
