For this month's Patch Tuesday Microsoft released 12 bulletins of which five were rated as Critical and seven as Important updates, addressing a total of 57 vulnerabilities across Internet Explorer, .NET Framework, Office, Windows and Exchange Server.
For those who need to prioritize deployments, there are 3 security bulletins that will need to be addressed right away.
MS13-009 addresses 13 issues across all supported versions of Internet Explorer and MS13-010 addresses issues in the Vector Markup Language (VML) which is used by all versions of Internet Explorer. Both of these issues could allow Remote Code Execution if a user viewed a specially crafted webpage using Internet Explorer.
MS13-020 affecting Windows XP resolves an issue in Microsoft Windows Object Linking and Embedding (OLE) Automation which could allow Remote Code Execution if a user opens a malicious RTF file with an embedded ActiveX control in either Word or WordPad.
In addition to the above mentioned bulletins, for the second time in less than a week, both Microsoft and Adobe released Critical-class bulletins (KB2805940 and APSB13-05) to update Flash Players. These updates address at least 16 distinct vulnerabilities including buffer overflow and use-after-free vulnerabilities that could lead to Code Execution.
All the above mentioned bulletins are now available for deployment via VMware vCenter Configuration Manager (VCM).
