Microsoft Security Updates for May 2012

Last Tuesday, May 8, Microsoft issued seven security bulletins that addressed a total of 23 security flaws. Three bulletins were labeled as critical. Systems affected:

  • Windows
  • .NET Framework
  • Microsoft Office
  • Silverlight

All but two bulletins addressed remote code execution vulnerabilities. While none of the bugs fixed in the update are currently being targeted, Microsoft said exploit code for eighteen of them was likely.

Among others, Microsoft patched flaws in Office for Mac 2011, a True Type Fonts vulnerability, a Rich Text Format mismatch vulnerability, six bugs in Excel, and various file format memory corruption, record heaps overflow, and remote code execution vulnerabilities.

MIT WAUS has released the patches to subscribers. They are also available through the operating system’s Windows Update tool.
