Executive Summary
This security update resolves vulnerabilities in Microsoft Windows. The more
severe of the vulnerabilities could allow remote code execution if a user
opens a specially crafted Journal file. Users whose accounts are configured to
have fewer user rights on the system could be less impacted than users who
operate with administrative user rights.
This security update is rated Critical for all supported releases of Windows
excluding Itanium editions, which are not affected. For more information, see
the Affected Software section.

Vulnerability Information
Multiple Windows Journal RCE Vulnerabilities
Remote code execution vulnerabilities exist in Microsoft Windows when a
specially crafted Journal file is opened in Windows Journal. An attacker who
successfully exploited the vulnerabilities could cause arbitrary code to
execute in the context of the current user. If a user is logged on with
administrative user rights, an attacker could take control of the affected
system. An attacker could then install programs; view, change, or delete data;
or create new accounts with full user rights. Users whose accounts are
configured to have fewer user rights on the system could be less impacted than
users who operate with administrative user rights.
For an attack to be successful, the vulnerabilities require that a user open a
specially crafted Journal file with an affected version of Windows Journal. In
an email attack scenario, an attacker could exploit the vulnerabilities by
sending a specially crafted Journal file to the user and by convincing the
user to open the file. The update addresses the vulnerabilities by modifying
how Windows Journal parses Journal files.
The update addresses the vulnerabilities by modifying how Internet Explorer
handles objects in memory. The following table contains links to the standard
entry for each vulnerability in the Common Vulnerabilities and Exposures list:
Vulnerability title CVE number Publicly disclosed Exploited
Windows Journal RCE Vulnerability CVE-2015-2513 No No
Windows Journal RCE Vulnerability CVE-2015-2514 No No
Windows Journal Integer Overflow CVE-2015-2519 No No
RCE Vulnerability
Windows Journal RCE Vulnerability CVE-2015-2530 No No
Windows Journal DoS Vulnerability - CVE-2015-2516
A denial of service vulnerability exists in Windows Journal when a specially
crafted Journal file is opened in Windows Journal. An attacker who
successfully exploited this vulnerability could cause data loss on the target
system. Note that the denial of service would not allow an attacker to execute
code or to elevate their user rights.
For an attack to be successful, a user must open a specially crafted Journal
file with an affected version of Windows Journal. In an email attack scenario,
an attacker could exploit the vulnerability by sending a specially crafted
Journal file to the user and by convincing the user to open the file. The
update addresses the vulnerability by correcting how Windows Journal manages
objects in memory.
Microsoft received information about this vulnerability through coordinated
vulnerability disclosure. When this security bulletin was issued, Microsoft
had not received any information to indicate that this vulnerability had been
publicly used to attack customers.
