Microsoft GDI+ CVE-2016-3354 Information Disclosure Vulnerability
Description
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. An attacker who successfully exploited this vulnerability could use the retrieved information to circumvent Address Space Layout Randomization (ASLR) in Windows, which helps guard against a broad class of vulnerabilities. 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, such as a remote code execution vulnerability, that is capable of leveraging the ASLR circumvention. To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The security update addresses the vulnerability, and helps protect the integrity of the ASLR security feature, by correcting how GDI handles memory addresses.
