Microsoft is preparing a bumper Patch Tuesday for next week, with 16 security bulletins that collectively address 34 vulnerabilities.
Nine of the bulletins earn the dread rating of critical, while the other seven grapple with flaws rated as important. All supported versions of Windows will need patching on 14 June along with various server-side software packages and applications, including the .NET framework and SQL Server. Internet Explorer, which is affected by two bulletins, will also need some fiddling under the bonnet.
Office suites also need to be updated thanks to a security fix for Excel that also affects the Mac OS X version of the product as well as virtually all versions of the spreadsheet software on Windows, including the most recent 2010 and 2011 editions of the software.
Tuesday will also mark the availability of security updates for Adobe Reader and Adobe Acrobat software.
The large number of security updates due this month follows a quiet Patch Tuesday last month, something that is settling in to become a regular pattern.
Wolfgang Kandek, CTO of security services firm Qualys, advised sys admins to plan ahead in order to minimise disruption.
"System administrators will need to plan closely as both workstations and servers are affected by the critical bulletins," Kandek said. "In addition applications such as Excel, Adobe Reader and Java will have to be taken into account this month," he added.
