Microsoft announced on Thursday that it plans to push out four patches -- none for "critical" vulnerabilities -- in the July round of fixes.
The four bulletins, all rated "important" in severity, address issues in SQL Server, Windows and Exchange, according to the advance notification.
There are two patches planned for Windows, one of which includes fixes for Vista. That same flaw could be exploited to execute remote code.
Andrew Storms, director of security operations at nCircle, said the round of fixes appears light, but IT security departments should not underestimate the vulnerabilities.
The Exchange bug, which could lead to privilege escalation, might be the one administrators need to worry about the most.
"There's so much to be had if you were to exploit an Exchange server at an enterprise," Storms told SCMaagzineUS.com on Thursday.
He added that SQL servers are also a critical component to businesses.
"Those two [Exchange and SQL] alone could throw a wrench in the works and not make this such an easy update for a lot of enterprises," Storms said.
Microsoft is also expected to release an updated version of the Windows Malicious Software Removal Tool, in addition to non-security updates to Windows Update, Microsoft Update and Windows Server Update Services.
Later this month, Microsoft plans to deliver an infrastructure upgrade to the Windows Update client, Bill Sisk, security response communications manager, said Thursday on the Security Response Center blog.
