Microsoft has posted fixes for Windows, Office and Silverlight in its latest security update.
The May edition of the company's monthly security update includes seven bulletins including two which are listed by the company as critical flaws and top deployment priorities.
The critical flaws addressed by the update include a remote code execution vulnerability present in Windows, Silverlight, Office and the .Net framework.
The second bulletin will address a critical flaw in Word which could be targeted for remote code execution.
A third critical patch, which addresses a remote code execution flaw in the .NET Framework has been classified by Microsoft as a slightly lower deployment priority, as have a pair of flaws in Office and the Visio Viewer rated as important.
The remaining two bulletins patch flaws in the Windows TCP/IP and Partition manager. Each have been rated by Microsoft as important security risks.
Dave Marcus, director of advanced research and threat intelligence with McAfee Labs noted the high risk of the vulnerabilities and recommends that administrators follow Microsoft's recommendations for deployment priorities.
"The bulletin affecting Microsoft Office is particularly important," Marcus explained.
"As we have seen with the Flashback Trojan, cybercriminals are using Microsoft Office to spread malware, so it’s important that Mac users update as soon as possible."
