Overview

Multiple vulnerabilities have been reported in the Microsoft Windows, which could be exploited by the attackers to gain elevated privileges and execute arbitrary code in the kernel mode or cause a Denial of Service condition on a targeted system.

Description

1.  Win32k Memory Corruption Vulnerability ( CVE-2013-3899   )

A vulnerability in the win32k.sys kernel-mode device driver due to improper validation of memory address values.  A local attacker could exploit this vulnerability by using a specially crafted application and a memory corruption error occurs when the software processes that application.

Successful exploitation of this vulnerability could allow the local attacker to gain elevated privileges  and execute the arbitrary code or compromise the system with the privileges of the targeted user.

2.  Win32k Use After Free Vulnerability ( CVE-2013-3902   )

An use-after-free vulnerability occurs in the win32k.sys kernel-mode device driver  due to improperly handle the objects in memory.  A local attacker could exploit this vulnerability by using a special crafted application and an use-after-free memory error condition occurs when the software processes that application.

Successful exploitation of this vulnerability could allow the local attacker to gain elevated privileges  and execute the arbitrary code in the kernel mode or compromise the system with the privileges of the targeted user.

3.  TrueType Font Parsing Vulnerability ( CVE-2013-3903   )

A denial of service vulnerability in the win32k.sys kernel-mode device driver in Microsoft Windows due to insufficient validation of array indexes while loading TrueType font files.  A remote attacker could exploit this vulnerability by embedding a specially crafted TrueType font file on a website and convince the user to visit the malicious website, the browser would attempt to render the font.

Successful exploitation of this vulnerability could allow the attacker to stop responding and restart the targeted system, resulting a Denial of Service condition.

4.  Port-Class Driver Double Fetch Vulnerability ( CVE-2013-3907   )

A gain elevated privileges vulnerability in the portcls.sys audio port-class device driver in Microsoft Windows due to improper handling of objects in memory. A local attacker could exploit this vulnerability by using a special crafted application and a double-fetch memory flaw may occur when the software processes that application.

Successful exploitation of this vulnerability could allow the local attacker to gain elevated privileges  and execute the arbitrary code in the kernel mode or compromise the system with the privileges of the targeted user.

5.  Win32k Integer Overflow Vulnerability ( CVE-2013-5058   )

An integer overflow vulnerability occurs in the win32k.sys kernel-mode device driver due to improper handling of objects in memory.  A local attacker could exploit this vulnerability by executing a specially crafted application which could cause to stop responding of the targeted system. 

Successful exploitation of this vulnerability could allow the attacker to cause a Denial of Service condition.
