Microsoft released nine security patches as part of its monthly patching cycle yesterday, with three of them described as “critical”.
The three critical patches all address vulnerabilities in the Windows operating system, and could allow a remote attacker to take control of a user’s machine without any user interaction.

Another four patches are described by Microsoft as “important” and two others fix “moderate” security threats.
One of the important fixes addresses a flaw in both the Windows operating system and the company’s Exchange e-mail server.
Last week Microsoft announced the planned introduction of Microsoft Client Protection, an integrated product designed to protect business desktops, laptops and file servers from current and emerging malware threats.
It also gave out details of the Microsoft Antigen anti-virus and anti-spam security software protection for messaging and collaboration servers.
