Microsoft had its biggest-ever patch on Tuesday, Aug. 10 and issued 14 new security bulletins. Eight of the security bulletins were rated "critical," of which four addressed high-priority vulnerabilities in Microsoft Office, Microsoft .NET Framework, Microsoft Silverlight, Microsoft’s MPEG Layer-3 audio codecs, and the Cinepak Codec used by Windows Media Player.
Of the six noncritical bulletins, which fixed vulnerabilities in Microsoft Windows and Office, all were rated "important." However, the vulnerabilities behind nearly all of the 14 bulletins apparently require considerable time and effort on the part of a cyber-criminal before they can be transformed into an exploit.
