Microsoft has released four new security bulletins in the July 2010 edition of patch Tuesday. These bulletins address five vulnerabilities. The last two bulletins affect Microsoft Office programs and each can lead to remote code execution on an affected machine. Windows 2000 and Windows XP SP2 have officially reached end of life support after today s patch Tuesday and Microsoft will not be supplying new Security Bulletins for these operating systems going forward. This light patch month is not uncommon, and has become expected, for a light patch Tuesday to follow a heavy patch Tuesday release.
