Vulnerability in Microsoft Graphics Component Could Allow Remote Code Execution

Number: AL13-006
Date: 6 November 2013


The purpose of this alert is to raise awareness of a reported vulnerability in the Microsoft Graphics component.


CCIRC is aware of reports of a remote code execution vulnerability in some Microsoft products that affects the way components handle specially crafted TIFF images.

An attacker could exploit this vulnerability by convincing a user to preview or open a specially crafted email message, a specially crafted file, or browse specially crafted web content. By successfully doing so, an attacker could possibly gain the same user rights as the current user. The severity of the situation ranges from attackers gaining access to user accounts with few rights to those accounts that operate with full administrative rights.

In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit this vulnerability. With no way to force the user to visit the site, the attacker would need to influence the user to visit the website by clicking on a link in an email message or Instant Messenger message or by opening an attachment.

With assistance from partners  in the Microsoft Active Protections Program (MAPP),  Microsoft is actively working to pass on information that they can use to provide extensive protection for its customers.

Upon completion of this investigation, Microsoft will take the appropriate action to help its customers. This may include the release of a security update through its monthly release process or providing an out-of-cycle security update, depending on customer needs.
