Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities :

- A flaw exists in the Win32k TrueType font parsing engine that allows an unauthenticated, remote attacker to execute arbitrary code by convincing a user to open a Word document containing malicious font data.
(CVE-2011-3402)

- A flaw exists in the t2embed.dll module when parsing TrueType fonts. An unauthenticated, remote attacker can exploit this, via a crafted TTF file, to execute arbitrary code. (CVE-2012-0159)

- A flaw exists in the .NET Framework due to a buffer allocation error when handling an XBAP or .NET application. An unauthenticated, remote attacker can exploit this, via a specially crafted application, to execute arbitrary code. (CVE-2012-0162)

- A flaw exists in the .NET Framework due to an error when comparing the value of an index in a WPF application. An unauthenticated, remote attacker can exploit this to cause a denial of service condition.
(CVE-2012-0164)

- A flaw exists in GDI+ when handling specially crafted EMF images that allows an unauthenticated, remote attacker to execute arbitrary code. (CVE-2012-0165)

- A heap buffer overflow condition exists in Microsoft Office in the GDI+ library when handling EMF images embedded in an Office document. An unauthenticated, remote attacker can exploit this to execute arbitrary code by convincing a user to open a specially crafted document. (CVE-2012-0167)

- A double-free error exists in agcore.dll when rendering XAML strings containing Hebrew Unicode glyphs of certain values. An unauthenticated, remote attacker can exploit this to execute arbitrary code by convincing a user to visit a specially crafted web page. (CVE-2012-0176)

- A privilege escalation vulnerability exists in the way the Windows kernel-mode driver manages the functions related to Windows and Messages handling. A local attacker can exploit this, via a specially crafted application, to gain elevated privileges.
(CVE-2012-0180)

- A privilege escalation vulnerability exists in the way the Windows kernel-mode driver manages Keyboard Layout files. A local attacker can exploit this, via a specially crafted application, to gain elevated privileges. (CVE-2012-0181)

- A privilege escalation vulnerability exists in the way the Windows kernel-mode driver manages scrollbar calculations. A local attacker can exploit this, via a specially crafted application, to gain elevated privileges. (CVE-2012-1848)

Solution

Microsoft has released a set of patches for Windows XP, 2003, Vista, 2008, 7, 2008 R2; Office 2003, 2007, and 2010; .NET Framework 3.0, 3.5.1, and 4.0; and Silverlight 4 and 5.
