Patch Analysis for February 2014

Microsoft released 7 bulletins for this month’s Patch Tuesday Analysis.  There are 4 critical bulletins that may allow arbitrary code execution.  Look into the patch for MS14-010 that fixes 24 vulnerabilities in Internet Explorer.  One of the vulnerabilities was publically disclosed and may allow arbitrary code execution.    MS14-007 addresses a vulnerability in Direct2d and MS14-011 addresses a vulnerability in VBScript both of which could leverage Internet Explorer as an attack path.  The last critical bulletin for this month is MS14-008 that fixes a vulnerability in Forefront Protection for Exchange.  This was a privately reported vulnerability that could allow arbitrary code execution when a maliciously crafted email is scanned.   There are several interesting important bulletins that should be noted.  MS14-009 patches a publically disclosed flaw in the .NET Framework that may allow an attacker to bypass security mechanisms.  This vulnerability has also been used in attacks.  MS14-005 is an information disclosure vulnerability that has been observed in the wild and publically disclosed.  MS14-006 is a denial of service vulnerability that requires an attacker to be on the same subnet and send large quantities of maliciously crafted IPv6 packets.
