Microsoft : Security Vulnerabilities, CVEs, Published In 2010 (Gain Privilege) CVSS score >= 6

The Client/Server Runtime Subsystem (aka CSRSS) in the Win32 subsystem in Microsoft Windows XP SP2 and SP3 and Server 2003 SP2, when a Chinese, Japanese, or Korean locale is enabled, does not properly allocate memory for transactions, which allows local users to gain privileges via a crafted application, aka "CSRSS Local Elevation of Privilege Vulnerability."

Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP1 and SP2, Windows Server 2008 SP2 and R2, and Windows 7 allow local users to gain privileges by leveraging access to a process with NetworkService credentials, as demonstrated by TAPI Server, SQL Server, and IIS processes, and related to the Windows Service Isolation feature. NOTE: the vendor states that privilege escalation from NetworkService to LocalSystem does not cross a "security boundary."

The memory-management implementation in the Virtual Machine Monitor (aka VMM or hypervisor) in Microsoft Virtual PC 2007 Gold and SP1, Virtual Server 2005 Gold and R2 SP1, and Windows Virtual PC does not properly restrict access from the guest OS to memory locations in the VMM work area, which allows context-dependent attackers to bypass certain anti-exploitation protection mechanisms on the guest OS via crafted input to a vulnerable application. NOTE: the vendor reportedly found that only systems with an otherwise vulnerable application are affected, because "the memory areas accessible from the guest cannot be leveraged to achieve either remote code execution or elevation of privilege and ... no data from the host is exposed to the guest OS."
