This month, Microsoft issued three security bulletins that address a total of eight vulnerabilities, one of which is rated as critical. Symantec expert Ben Greenbaum, a senior research manager, shares his expertise on the vulnerabilities in a quick video segment included here.

This month’s critical vulnerability can allow an attacker to gain complete control of a user’s machine if they open an HTML e-mail, e-mail attachment or visit a Web site infected with a .WMF or .EMF picture file.

Symantec strongly encourages users to patch their system against these vulnerabilities. In addition, enterprises are encouraged to consider implementing an automated patch management solution to help mitigate risk.
