Critical patches issued for Excel, Active Directory and .NET.
Microsoft
has released a total of seven patches in its monthly ‘Patch Tuesday’ security update, with three of the vulnerable products covered marked as ‘critical’.
The most significant problems are in
Excel
spreadsheet software, which has three separate vulnerabilities fixed this month, each allowing remote code execution.
Active Directory
and the
.NET Framework
each have two flaws fixed, again mostly allowing remote exploitation and in one case data disclosure.
Other patches cover problems with
IIS

MS Publisher
