Microsoft readies two Windows security updates

摘要

Microsoft plans to issue two security updates for its Windows operating system products Tuesday as part of its regular software patch cycle. One of the updates is considered critical for Windows Vista and XP users because the flaw it fixes could be used by attackers to install unauthorized software on a victim's computer.The second update, rated important for all Windows users, could allow an attacker to run software with a higher level of privilege on a system than would normally be allowed.
