Microsoft Security Bulletin MS14-085 - Important
Vulnerability in Microsoft Graphics Component Could Allow Information
Disclosure (3013126)
Published: December 9, 2014
Version: 1.0
Executive Summary
This security update resolves a publicly disclosed vulnerability in Microsoft
Windows. The vulnerability could allow information disclosure if a user
browses to a website containing specially crafted JPEG content. An attacker
could use this information disclosure vulnerability to gain information about
the system that could then be combined with other attacks to compromise the
system. The information disclosure vulnerability by itself does not allow
arbitrary code execution. However, an attacker could use this information
disclosure vulnerability in conjunction with another vulnerability to bypass
security features such as Address Space Layout Randomization (ASLR).

Vulnerability Information
Information Disclosure Vulnerability - CVE-2014-6355
An information disclosure vulnerability exists in the Microsoft Graphics
Component that could allow an attacker to more reliably predict the memory
offsets of specific instructions in a given call stack. The vulnerability
is caused when the Microsoft Graphics Component improperly handles the
decoding of JPEG images in memory. An attacker could use this information
disclosure vulnerability to gain information about the system that could
then be combined with other attacks to compromise the system. The
information disclosure vulnerability by itself does not allow arbitrary
code execution. However, an attacker could use this information disclosure
vulnerability in conjunction with another vulnerability to bypass security
features such as Address Space Layout Randomization (ASLR). The security
update addresses the vulnerability by changing how memory is initialized
and managed when JPEG images are decoded.
