It appears that no less than seven security patches will form part of July's Microsoft monthly security update. In each case, every patch contains fixes for one or more vulnerabilities that could be used as an attack vector by malware if properly exploited.
In total, the updates for this will month will include four Microsoft Security Bulletins affecting Microsoft Windows, of which the highest is rated critical. The updates will be detectable using the Microsoft Baseline Security Analyzer and the Enterprise Scan Tool, and some of the updates will require a reboot. There are also three Microsoft Security Bulletins affecting Microsoft Office, again with the highest being critical. These may also require a restart. Additionally, there will be an updated version of the Microsoft Windows Malicious Software Removal Tool.
This round of updates continues Microsoft's policy of releasing security patches on the second Tuesday of every month, announced in advance so as to give IT staff time to plan the deployment of the updates.
