November 2012 Microsoft Security Bulletin Release
by Alice CullenThis month there are nine security bulletins in the Microsoft Security Bulletin release:
- 4 bulletin is rated as Critical
- 1 bulletins are rated as Important
- 5 bulletins addressing vulnerabilities that could lead to Remote Code Execution
| Bulletin ID | Maximum Severity Rating and Vulnerability Impact | Restart Requirement | Affected Software |
|---|---|---|---|
| MS12-071 | Critical Remote Code Execution |
Requires restart | Microsoft Windows, Internet Explorer |
| Cumulative Security Update for Internet Explorer (2761451) This security update resolves three 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 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. |
|||
| MS12-072 | Critical Remote Code Execution |
Requires restart | Microsoft Windows |
| Vulnerabilities in Windows Shell Could Allow Remote Code Execution (2727528) This security update resolves two privately reported vulnerabilities in Microsoft Windows. The vulnerabilities could allow remote code execution if a user browses to a specially crafted briefcase in Windows Explorer. An attacker who successfully exploited this vulnerability could run arbitrary code as the current user. If the current user is logged on with administrative user rights, an attacker could take complete control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. 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. |

| MS12-074 | Critical Remote Code Execution |
May require restart | Microsoft Windows, Microsoft .NET Framework |
| Vulnerabilities in .NET Framework Could Allow Remote Code Execution (2745030) This security update resolves five privately reported vulnerabilities in the .NET Framework. The most severe of these vulnerabilities could allow remote code execution if an attacker convinces the user of a target system to use a malicious proxy auto configuration file and then injects code into the currently running application. |
|||
| MS12-075 | Critical Remote Code Execution |
Requires restart | Microsoft Windows |
| Vulnerabilities in Windows Kernel-Mode Drivers Could Allow Remote Code Execution (2761226) This security update resolves three privately reported vulnerabilities in Microsoft Windows. The most severe of these vulnerabilities could allow remote code execution if a user opens a specially crafted document or visits a malicious webpage that embeds TrueType font files. An attacker would have to convince users to visit the website, typically by getting them to click a link in an email message that takes them to the attacker’s website. |
|||
| MS12-076 | Important Remote Code Execution |
May require restart | Microsoft Office |
| Vulnerabilities in Microsoft Excel Could Allow Remote Code Execution (2720184) This security update resolves four privately reported vulnerabilities in Microsoft Office. The vulnerabilities could allow remote code execution if a user opens a specially crafted Excel file with an affected version of Microsoft Excel. An attacker who successfully exploited the 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. |
|||
| MS12-073 | Moderate Information Disclosure |
May require restart | Microsoft Windows |
| Vulnerabilities in Microsoft Internet Information Services (IIS) Could Allow Information Disclosure (2733829) This security update resolves one publicly disclosed vulnerability and one privately reported vulnerability in Microsoft Internet Information Services (IIS). The more severe vulnerability could allow information disclosure if an attacker sends specially crafted FTP commands to the server. |

In summary, we are likely to see updates requiring reboots of servers this month. As usual, as a UKFast customer, you will benefit from these updates being applied automatically unless you have opted out of this service.
