**1.0 Introduction**
Microsoft has released 9 security bulletins for June 2012. Three of them are rated Critical and six of them are Important
**2.0 The list of the critical vulnerabilities are as below:**
- **2.1 Vulnerability in Microsoft XML Core Services Could Allow Remote Code Execution**
This security update resolves a publicly disclosed vulnerability in Microsoft XML Core Services. The vulnerability could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker would have no way to force users to visit such a website. Instead, an attacker would have to convince users to visit the website, typically by getting them to click a link in an email message or Instant Messenger message that takes the user to the attacker's website.
Patch:[http://go.microsoft.com/fwlink/?LinkID=254824](http://support.microsoft.com/kb/2719615)
- **2.2 Cumulative Security Update for Internet Explorer**
This security update resolves two privately reported vulnerabilities in Internet Explorer. The vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who successfully exploited any of these vulnerabilities could gain the same user rights as the current user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
Patch: <http://go.microsoft.com/fwlink/?LinkId=254377>
- **2.3 Vulnerability in Microsoft Data Access Components Could Allow Remote Code Execution**
This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user views a specially crafted webpage. An attacker who successfully exploited this vulnerability could gain the same user rights as the current user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
Patch: <http://go.microsoft.com/fwlink/?LinkId=254441>
**3.0 The list of the Important vulnerabilities are as below:**
- **3.1 Vulnerability in Visual Basic for Applications Could Allow Remote Code Execution**
This security update resolves one publicly disclosed vulnerability in Microsoft Visual Basic for Applications. The vulnerability could allow remote code execution if a user opens a legitimate Microsoft Office file (such as a .docx file) that is located in the same directory as a specially crafted dynamic link library (DLL) file. An attacker could then install programs; view, change, or delete data; or create new accounts that have full user rights. If a user is logged on with administrative user rights, an attacker could take complete control of the affected system. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
Patch: <http://go.microsoft.com/fwlink/?LinkId=252510>
- **3.2 Vulnerabilities in Windows Kernel-Mode Drivers Could Allow Elevation of Privilege**
This security update resolves one publicly disclosed and one privately reported vulnerability in Microsoft Windows. The vulnerabilities could allow elevation of privilege if an attacker logs on to the system and runs a specially crafted application. An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability.
Patch: <http://go.microsoft.com/fwlink/?LinkId=254380>
- **3.3 Vulnerability in Windows Shell Could Allow Remote Code Execution**
- This security update resolves one privately reported vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user opens a file or directory with a specially crafted name. An attacker who successfully exploited this vulnerability could gain the same user rights as the current user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
Patch: <http://go.microsoft.com/fwlink/?LinkId=239507>
- **3.4 Vulnerability in TLS Could Allow Information Disclosure**
This security update resolves a publicly disclosed vulnerability in TLS. The vulnerability could allow information disclosure if an attacker intercepts encrypted web traffic served from an affected system. All cipher suites that do not use CBC mode are not affected.
Patch: <http://go.microsoft.com/fwlink/?LinkId=251035>
- **3.5 Vulnerabilities in SharePoint Could Allow Elevation of Privilege**
This security update resolves one publicly disclosed and five privately reported vulnerabilities in Microsoft SharePoint and Windows SharePoint Services. The most severe vulnerabilities could allow elevation of privilege if a user clicks a specially crafted URL that takes the user to a targeted SharePoint site.
Patch: <http://go.microsoft.com/fwlink/?LinkId=251611>
- **3.6 Vulnerability in Microsoft Office for Mac Could Allow Elevation of Privilege**
This security update resolves one publicly disclosed vulnerability in Microsoft Office for Mac. The vulnerability could allow elevation of privilege if a malicious executable is placed on an affected system by an attacker, and then another user logs on later and runs the malicious executable. An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability.
Patch: <http://go.microsoft.com/fwlink/?LinkID=255000>
**4.0 Recommendation**
Users are recommended to perform the update immediately. All of the patches could be done almost automatically via the Windows Update application.
