This security update is rated Important for Internet Explorer on Windows clients and Internet Explorer 9 for Windows 2008 R2, and Low for Internet Explorer on Windows servers.

"The update resolves three privately reported vulnerabilities in Internet Explorer. The most severe vulnerabilities could allow remote code execution if a user visits a specially crafted Web page using IE. An attacker who successfully exploited this vulnerability could run a malicious application on the affected system. Users whose accounts are configured to have fewer user rights on the system could be less affected than users who operate with administrative user rights," informs Microsoft.

Customers who do not have enabled automatic updating, can enable it (Start Menu, type "Windows Update").

"Helompy is a worm that propagates by copying itself to the root of removable drives, and its main payload is to record account credentials and login information and send them to a remote server, where the attacker could retrieve them for use," informed MMPC.
