Microsoft Security Advisory (2490606): Vulnerability in Graphics Rendering Engine Could Allow Remote
Revision Note: V1.2 (January 19, 2011): Clarified that the Modify the Access Control List (ACL) on shimgvw.dll workaround only applies to Windows XP and Windows Server 2003 systems and added a new workaround, Disable viewing of thumbnails in Windows Explorer on Windows Vista and Windows Server 2008 systems. Advisory Summary:Microsoft is investigating new public reports of a vulnerability in the Windows Graphics Rendering Engine. An attacker who successfully exploited this vulnerability could run arbitrary code in the security context of the logged-on user. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

DateTime::TimeZone::Local::Win32(3)			User Contributed Perl Documentation		       DateTime::TimeZone::Local::Win32(3)

NAME

       DateTime::TimeZone::Local::Win32 - Determine the local system's time zone on Windows

VERSION

       version 1.51

SYNOPSIS

	 my $tz = DateTime::TimeZone->new( name => 'local' );

	 my $tz = DateTime::TimeZone::Local->TimeZone();

DESCRIPTION

       This module provides methods for determining the local time zone on a Windows platform.

HOW THE TIME ZONE IS DETERMINED

       This class tries the following methods of determining the local time zone:

       o   $ENV{TZ}

	   It checks $ENV{TZ} for a valid time zone name.

       o   Windows Registry

	   When using the registry, we look for the Windows time zone and use a mapping to translate this to an Olson time zone name.

	   o	   Windows Vista and 2008

		   We look in "SYSTEM/CurrentControlSet/Control/TimeZoneInformation/" for a node named "/TimeZoneKeyName". If this exists, we use
		   this key to look up the Olson time zone name in our mapping.

	   o	   Windows NT, Windows 2000, Windows XP, Windows 2003 Server

		   We look in "SOFTWARE/Microsoft/Windows NT/CurrentVersion/Time Zones/" and loop through all of its sub keys.

		   For each sub key, we compare the value of the key with "/Std" appended to the end to the value of
		   "SYSTEM/CurrentControlSet/Control/TimeZoneInformation/StandardName". This gives us the English name of the Windows time zone,
		   which we use to look up the Olson time zone name.

	   o	   Windows 95, Windows 98, Windows Millenium Edition

		   The algorithm is the same as for NT, but we loop through the sub keys of "SOFTWARE/Microsoft/Windows/CurrentVersion/Time
		   Zones/"
