Patch Analysis for June 2013

Five security bulletins have been released by Microsoft. Most of the patched vulnerabilities primarily affect workstations and Terminal Servers. The one exception is MS13-050 which patches a vulnerability in print spooler components. If the print spooler is not needed on your server, disabling it will help protect it. Even after the patch is applied we recommend disabling all unnecessary services to reduce the target footprint. MS13-047 is a cumulative update for Internet Explorer patching multiple vulnerabilities (19). MS13-051 patches a vulnerability that is in both Office 2003 and Office for Mac 2011. Microsoft reports that there are current targeted exploits taking place. Microsoft's delayed EMET 4.0 (Enhanced Mitigation Experience Toolkit) that I mentioned last month will help with this.

MS13-048 and MS13-049 patch vulnerabilities in the core of the Windows OS, that is the kernel and kernel mode drivers. Although the danger is there, Microsoft reports that exploit code for these is unlikely.

Unwanted and unknown applications can introduce malware, decrease PC performance, consume disk space, reduce network bandwidth and ultimately reduce IT and user productivity. With the free Application Scanner Tool from Lumension you can:

  • Discover all applications and executables in your endpoint environment
  • Validate the integrity of applications and files against known vendor provenance; and
  • Identify and report on systems at risk with the most unknown executables and the most prevalent applications and unknown executables in your organization

"I liked your high level overview of patches in the table. There are so many sources of patch information which can be very specific or surrounded by other stuff that it’s refreshing to get everything summarised like this. The “Randy’s Recommendation” comment is useful starting point too. Please keep up the good work."
