Microsoft is planning a major raft of security fixes this
month in its monthly Patch Tuesday update.
The update will occur on Wednesday, NZ time, addressing 25
problems, five of the vulnerabilities being rated Critical. Some apply to
enterprise applications including Microsoft Office and Exchange. Affected
operating systems include Windows 2000, XP, Vista, 2003, 2008 and Windows 7.
The critical flaws could allow a remote attacker to take control
of a machine, install malicious software, or contribute to a denial-of-service
The fixes will be delivered via automatic updates and most
will require the user to restart their computer. If you don’t receive automatic
updates, you can get more information here.
