The software giant will address 22 vulnerabilities through 12 patches, three of which were rated as critical. The other nine fell into the “important” category.
The issues affected Microsoft Windows, Internet Explorer, Office, Visual Studio and IIS.
“As part of this month's update, we'll be addressing issues related to two recent Security Advisories, 2490606 – a public vulnerability affecting the Windows Graphics Rendering Engine – and 2488013 – a public vulnerability affecting Internet Explorer,” said Angela Gunn, communications manager at Microsoft, on the company’s security blog.
“Additionally, we will be addressing an issue affecting FTP service in IIS 7.0 and 7.5.”
Last Patch Tuesday, Microsoft only released two bulletins, one of which fixed a critical flaw affecting all versions of Windows. Users had hoped for the Windows Graphics Rendering Engine fix last month but it was pushed into next week’s update.
