PDF Library (3182248)
Executive Summary
This security update resolves a vulnerability in Microsoft Windows. The
vulnerability could allow remote code execution if a user views specially
crafted PDF content online or opens a specially crafted PDF document. An
attacker who successfully exploited the vulnerability could gain the same user
rights as the current user. If the current user is logged on with
administrative user rights, an attacker could take control of an affected
system. An attacker could then install programs; view, change, or delete data;
or create new accounts with full user rights.
This security update is rated Critical for all supported editions of Windows
8.1, Windows Server 2012, Windows RT 8.1, Windows Server 2012 R2, and Windows
10.
Affected Software
Windows 8.1
Windows Server 2012
Windows Server 2012 R2
Windows RT 8.1 [1]
Windows 10 [2]
[1] This update is only available via Windows Update.
[2] Windows 10 updates are cumulative. The monthly security release includes
all security fixes for vulnerabilities that affect Windows 10, in addition
to non-security updates. The updates are available via the Microsoft Update
Catalog.
Vulnerability Information
Microsoft PDF Remote Code Execution Vulnerability - CVE-2016-3319
A remote code execution vulnerability exists when Microsoft Windows PDF
Library improperly handles objects in memory. The vulnerability could corrupt
memory in a way that enables an attacker to execute arbitrary code in the
context of the current user. An attacker who successfully exploited the
vulnerability could gain the same user rights as the current user. If the
current user is logged on with administrative user rights, an attacker could
take control of an affected system. An attacker could then install programs;
view, change, or delete data; or create new accounts with full user rights.
To exploit the vulnerability on Windows 10 systems with Microsoft Edge set as
the default browser, an attacker could host a specially crafted website that
contains malicious PDF content and then convince users to view the website.
The attacker could also take advantage of compromised websites, or websites
that accept or host user-provided content or advertisements, by adding
specially crafted PDF content to such sites. Only Windows 10 systems with
Microsoft Edge set as the default browser can be compromised simply by viewing
a website. The browsers for all other affected operating systems do not
automatically render PDF content, so an attacker would have no way to force
users to view attacker-controlled content. Instead, an attacker would have to
convince users to open a specially crafted PDF document, typically by way of
an enticement in an email or instant message or by way of an email attachment.
The update addresses the vulnerabilities by modifying how affected systems
handle objects in memory.
