Microsoft has released a security bulletin and software updates to address the Microsoft Graphics Component remote code execution vulnerability.
A vulnerability in the Microsoft Graphics Component in multiple Microsoft products could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system.
The vulnerability exists because the affected software improperly handles crafted Tagged Image File Format (TIFF) files. An unauthenticated, remote attacker could exploit this vulnerability by convincing a user to visit a malicious website that is designed to submit crafted TIFF files to be processed by the affected software. If successful, the attacker could execute arbitrary code with the privileges of a targeted user, which could result in a complete system compromise if the user holds administrative privileges.
Microsoft has confirmed the vulnerability in a security bulletin and released software updates.
The following Microsoft products are affected:
Windows Vista SP2
Windows Vista x64 Edition SP2
Windows Server 2008 for 32-bit and x64-based Systems SP2
Windows Server 2008 for Itanium-based Systems SP2
Microsoft Office 2003 and 2007 SP3
Microsoft Office 2010 32-bit and 64-bit editions SP2 and prior
Microsoft Office Compatibility Pack SP3
Microsoft Lync 2010 32-bit and 64-bit editions
Microsoft Lync 2010 Attendee
Microsoft Lync 2013 32-bit and 64-bit editions
Microsoft Lync Basic 2013 32-bit and 64-bit editions
To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site and use misleading language or instructions to persuade the user to follow the provided link.
This vulnerability has been exploited in the wild in targeted attacks and used in Operation HangOver attacks as documented in IntelliShield Alert 29383. This vulnerability has also been exploited by the Arx group, which has been identified by various reports for delivering the Citadel trojan as documented in IntelliShield Alert 28396. Users are advised to implement the Microsoft Fix It solution until a software update becomes available from Microsoft because exploit activity for this vulnerability is widespread and currently active.
Microsoft has released a security bulletin at the following link: MS13-096
An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary code with the privileges of a targeted user. Successful exploitation could result in a complete system compromise.
The vulnerability is due to improper handling of crafted TIFF files by the affected software.
An unauthenticated, remote attacker could exploit this vulnerability by convincing a user to visit a malicious website that is designed to submit crafted TIFF files to be processed by the affected software. If successful, the attacker could execute arbitrary code with the privileges of a targeted user, which could result in a complete system compromise if the user holds administrative privileges.
Administrators are advised to apply the appropriate updates.
Administrators are advised to allow only trusted users to have network access.
Users are advised not to open email messages from suspicious or unrecognized sources. If users cannot verify that links or attachments included in email messages are safe, they are advised not to open them.
Administrators may consider disabling the TIFF codec to prevent TIFF files from being displayed. Details on performing this action are described in the "Workarounds" section of the security advisory.
Administrators may consider implementing the Fix It solution as a workaround option at the following link: Fix It 51004 or 51005
Administrators are advised to monitor critical systems.
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.
