Windows GDI+ Information Disclosure Vulnerability

An information disclosure vulnerability exists in the way that the Windows Graphics Device Interface (GDI) handles objects in memory, allowing an attacker to retrieve information from a targeted system. By itself, the information disclosure does not allow arbitrary code execution; however, it could allow arbitrary code to be run if the attacker uses it in combination with another vulnerability.

To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application.

Note that where the severity is indicated as Critical in the Affected Products table, the Preview Pane is an attack vector for this vulnerability.

The security update addresses the vulnerability by correcting how GDI handles memory addresses.
