Version Summary:Microsoft Windows Kernel contains a vulnerability that could allow an unauthenticated, remote attacker to access sensitive information on a targeted system. Updates are available.
 
 
Description
A vulnerability in Microsoft Windows could allow an unauthenticated, remote attacker to access sensitive information.

The vulnerability is due to improper memory operations performed by the affected software. An attacker could exploit the vulnerability by convincing a user to open a malicious file. A successful exploit could allow the attacker to access kernel memory addresses. This ability could allow the attacker to access sensitive information. The attacker could use the information gained to launch additional attacks.

Microsoft has confirmed the vulnerability in a security bulletin and released software updates.
 
Warning Indicators
The following Microsoft products are affected:
  • Windows XP SP3
  • Windows Server 2003 SP2
  • Windows Vista SP2
  • Windows Server 2008 for 32-bit Systems SP2
  • Windows 7 for 32-bit Systems SP1
  • Windows 8 for 32-bit Systems
 
IntelliShield Analysis
To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site or persuade a user to open a malicious file intended to submit malicious input to the affected software.

Microsoft has resolved the vulnerability by by modifying how Windows handles certain page fault system calls.

The Cisco Applied Intelligence team has created an Applied Mitigation Bulletin to address vulnerabilities that Microsoft disclosed in the June 2013 security bulletin release. This Cisco bulletin, which assists administrators in identifying or mitigating these vulnerabilities using Cisco devices, is available at the following link: Cisco Applied Mitigation Bulletin: Microsoft Security Bulletin Release for June 2013

Impact
An unauthenticated, remote attacker could exploit the vulnerability to access kernel memory addresses. This ability could allow the attacker to access sensitive information. The attacker could use the information gained to launch additional attacks.
 
Technical Information
The vulnerability is due to improper memory operations performed by the affected software related to page fault system calls.

An unauthenticated, remote attacker could exploit the vulnerability by providing a crafted file to a user and using misleading language or instructions in an attempt to persuade the user to open the file. When the malicious file is processed by the affected software, a memory error could occur that the attacker could use to access kernel memory addresses. This ability could allow the attacker to access sensitive information. The attacker could may also use the information gained to launch additional attacks.
 
Safeguards
Administrators are advised to apply the appropriate updates.

Administrators are advised to allow only trusted users to have network access.

Administrators may consider using the Microsoft Baseline Security Analyzer (MBSA) scan tool to identify common security misconfigurations and missing security updates on system endpoints.

Administrators may consider configuring the Microsoft Enhanced Mitigation Experience Toolkit (EMET) to work with the affected software.

Users are advised not to open e-mail messages from suspicious or unrecognized sources. If users cannot verify that links or attachments included in e-mail messages are safe, they are advised not to open them.

Users are advised not to visit websites or follow links that have suspicious characteristics or cannot be verified as safe.

Administrators are advised to use an unprivileged account when browsing the Internet.

Administrators are advised to monitor critical systems.
 
Patches/Software
Microsoft customers can obtain updates directly by using the links in the security bulletin. These updates are also distributed by Windows automatic update features and available on the Microsoft Update service. Microsoft Windows Server Update Services (WSUS), Systems Management Server, and System Center Configuration Manager can assist administrators in deploying software updates.
