Description

The remote host contains a version of the Windows kernel that is affected by multiple vulnerabilities :

  • A failure of the Windows kernel to properly validate changes in certain kernel objects allows a local user to run arbitrary code in kernel mode. (CVE-2009-1123)

  • Insufficient validation of certain pointers passed from user mode allows a local user to run arbitrary code in kernel mode. (CVE-2009-1124)

  • A failure to properly validate an argument passed to a Windows kernel system call allows a local user to run arbitrary code in kernel mode. (CVE-2009-1125)

  • Improper validation of input passed from user mode to the kernel when editing a specific desktop parameter allows a local user to run arbitrary code in kernel mode. (CVE-2009-1126)
