Microsoft released 13 patches Tuesday to fix 22 security flaws affecting several of its programs, including Internet Explorer and Windows.
Of the 13 separate security bulletins, two of them, for Windows and Internet Explorer, are classified as "critical," meaning an online attacker could exploit these bugs to execute malicious code on a target's computer.
The remaining 11 bulletins are labeled "important" or "moderate," and could allow for an outside party to gain privileged access to a victim's computer if left unpatched, Microsoft wrote on its TechNet blog.

The software updates, part of Microsoft's monthly "Patch Tuesday," covered flaws in Office, .NET and Visual Studio as well. Along with the patches, the software giant also rolled out an updated version of its Microsoft Windows Malicious Software Removal Tool.
The software updates and the malware removal tool are all available from Microsoft's website.
