General Information

Executive Summary

  This security update resolves one publicly disclosed and one privately 
  reported vulnerability in Microsoft Windows. The vulnerabilities could 
  allow elevation of privilege if an attacker logged on to the system and 
  then ran a specially crafted application. To exploit either 
  vulnerability, an attacker must have valid logon credentials and be able 
  to log on locally. The vulnerabilities could not be exploited remotely 
  or by anonymous users.

  This security update is rated Important for all supported editions of 
  Microsoft Windows 2000, Windows XP, Windows Server 2003, Windows Vista, 
  Windows Server 2008, and Windows 7 for 32-bit Systems. 

  The security update addresses the vulnerabilities by ensuring that the 
  Windows Kernel handles exceptions properly. 

  This security update also addresses the vulnerability first described 
  in Microsoft Security Advisory 979682.

Vulnerability Information

Windows Kernel Exception Handler Vulnerability - CVE-2010-0232

  An elevation of privilege vulnerability exists in the Windows Kernel due 
  to the way the kernel handles certain exceptions. An attacker who 
  successfully exploited this vulnerability could run arbitrary code in 
  kernel mode. An attacker could then install programs; view, change, or 
  delete data; or create new accounts with full user rights.

Windows Kernel Double Free Vulnerability - CVE-2010-0233

  An elevation of privilege vulnerability exists in the Windows Kernel due 
  to a double free condition. An attacker who successfully exploited this 
  vulnerability could run arbitrary code in kernel mode. An attacker could 
  then install programs; view, change, or delete data; or create new accounts 
  with full user rights.
