Microsoft Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, Windows RT Gold and 8.1, Windows 10, Office 2007 SP3 and 2010 SP2, Live Meeting 2007 Console, Lync 2010, Lync 2010 Attendee, Lync 2013 SP1, Lync Basic 2013 SP1, and Silverlight before 5.1.40728 allow remote attackers to execute arbitrary code via a crafted TrueType font, aka "TrueType Font Parsing Vulnerability."

The remote Windows host is affected by multiple vulnerabilities :

  - Multiple remote code execution vulnerabilities exist due     to the Windows Adobe Type Manager Library not properly     handling specially crafted OpenType fonts. An attacker     can exploit these, by using a crafted document or web     page with embedded OpenType fonts, to execute arbitrary     code in the context of the current user. (CVE-2015-2432,     CVE-2015-2458, CVE-2015-2459, CVE-2015-2460,     CVE-2015-2461, CVE-2015-2462)

  - Multiple remote code execution vulnerabilities exist in     various components of Windows, .NET Framework, Office,     Lync, and Silverlight due to a failure to properly handle     TrueType fonts. An attacker can exploit these, by using     a crafted document or web page with embedded TrueType     fonts, to execute arbitrary code in the context of the     current user. (CVE-2015-2435, CVE-2015-2455,     CVE-2015-2456 CVE-2015-2463, CVE-2015-2464)

  - A remote code execution vulnerability exists due to     Microsoft Office not properly handling Office Graphics     Library (OGL) fonts. An attacker can exploit this, by     using a crafted document or web page with embedded OGL     fonts, to execute arbitrary code in the context of the     user. (CVE-2015-2431)

  - A security feature bypass vulnerability exists due to     a failure by the Windows kernel to properly initialize     a memory address. An attacker, using a specially crafted     application, can exploit this issue to bypass Kernel     Address Space Layout Randomization (KASLR) and retrieve     the base address of the kernel driver. (CVE-2015-2433)

  - An elevation of privilege vulnerability exists due to     a flaw in the Windows Client/Server Run-time Subsystem     (CSRSS) when terminating a process when a user logs off.
    An attacker can exploit this vulnerability to run code     that monitors the actions of users who log on to the     system, allowing the disclosure of sensitive information     which could be used to elevate privileges or execute     code. (CVE-2015-2453)

  - A security feature bypass vulnerability exists due to     the Windows kernel-mode driver not properly validating     and enforcing impersonation levels. An attacker can     exploit this to gain elevated privileges on a targeted     system. (CVE-2015-2454)

  - A security feature bypass vulnerability exists due to     the Windows shell not properly validating and enforcing     impersonation levels. An attacker can exploit this to     bypass impersonation-level security and gain elevated     privileges on a targeted system. (CVE-2015-2465)

The Microsoft Silverlight installed on the remote Mac OS X host is affected by multiple remote code execution vulnerabilities related to flaws in handling specially crafted TrueType fonts.
