Microsoft's Patch Tuesday for March Contains Just One Critical Fix
The critical fix applies to all versions of Windows since XP and plugs up a security hole that could allow an attacker to gain control of an infected system remotely.
"Organizations will have to reboot after applying the critical patch, which indicates that it is fix for a kernel level bug," said Marcus Carey, a security researcher at Rapid7. "There are two important bulletins that effect the Windows family as well."
This roundup of half a dozen security bulletins brings the total to 22 for the year, compared to 17 that were issued through March 2011. And while this is a relatively light month in terms of Patch Tuesday updates, it contains twice as many security bulletins as last year.
