Windows Imaging Component Information Disclosure Vulnerability

An information disclosure vulnerability exists in Windows when the Windows Imaging Component fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system.

There are multiple ways an attacker could exploit this vulnerability:

• In a web-based attack scenario, an attacker could host a specially crafted website designed to exploit this vulnerability and then convince a user to view the website. An attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by getting them to click a link in an email or instant message that takes users to the attacker’s website or by opening an attachment sent through email.
• In a file-sharing attack scenario, an attacker could provide a specially crafted document file designed to exploit this vulnerability and then convince a user to open the document file.

The security update addresses the vulnerability by correcting how the Windows Imaging Component handles objects in the memory.
