Microsoft Security Bulletin MS13-036 - Important

Vulnerabilities in Kernel-Mode Driver Could Allow Elevation Of Privilege 
(2829996)

Published Date: April 9, 2013

Version: 1.0

General Information

Executive Summary

This security update resolves three privately reported vulnerabilities and one
publicly disclosed vulnerability in Microsoft Windows. The most severe of 
these vulnerabilities could allow elevation of privilege if an attacker logs 
on to the system and runs a specially crafted application. An attacker must 
have valid logon credentials and be able to log on locally to exploit the most
severe vulnerabilities.

This security update is rated Important for all supported releases of 
Microsoft Windows.

Vulnerability Information

Win32k Race Condition Vulnerability - CVE-2013-1283

An elevation of privilege vulnerability exists when the Windows kernel-mode 
driver improperly handles objects in memory. An attacker who successfully 
exploited this vulnerability could gain elevated privileges and read arbitrary
amounts of kernel memory.

Win32k Font Parsing Vulnerability - CVE-2013-1291

A denial of service vulnerability exists when Windows fails to handle a 
specially crafted font file. The vulnerability could cause the computer to 
stop responding and restart.

Win32k Race Condition Vulnerability - CVE-2013-1292 An elevation of privilege
vulnerability exists when the Windows kernel-mode driver improperly handles 
objects in memory. An attacker who successfully exploited this vulnerability 
could gain elevated privileges and read arbitrary amounts of kernel memory.

NTFS NULL Pointer Dereference Vulnerability - CVE-2013-1293

An elevation of privilege vulnerability exists when the NTFS kernel-mode 
driver improperly handles objects in memory. An attacker who successfully 
exploited this vulnerability could run arbitrary code in kernel mode. An 
attacker could then install programs; view, change, or delete data; or create
new accounts with full administrative rights.
