Detailed Description |
The Hotfix (MS15-023, 3034344) for 'Vulnerabilities in Kernel-Mode Driver Could Allow Elevation of Privilege' has not been applied. This security update resolves vulnerabilities in Microsoft Windows. The most severe of the vulnerabilities could allow elevation of privilege if an attacker logs on to the system and runs a specially crafted application designed to increase privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full administrative rights.
- Microsoft Windows Kernel Memory Disclosure Vulnerability(CVE-2015-0077) An information disclosure vulnerability exists in the Windows kernel-mode driver that could allow the disclosure of kernel memory contents to an attacker. This vulnerability is caused when the Windows kernel-mode driver fails to initialize function buffers in a manner that removes the results of previous function calls.
- Win32k Elevation of Privilege Vulnerability(CVE-2015-0078) An elevation of privilege vulnerability exists in the Windows kernel-mode driver that is caused when the kernel-mode driver fails to properly validate the calling thread's token.
- Microsoft Windows Kernel Memory Disclosure Vulnerability(CVE-2015-0094) An information disclosure vulnerability exists in the Windows kernel-mode driver that could allow the disclosure of kernel memory contents to an attacker. This vulnerability is caused when the Windows kernel-mode driver leaks private address information during a function call.
- Microsoft Windows Kernel Memory Disclosure Vulnerability(CVE-2015-0095) An information disclosure vulnerability exists in the Windows kernel-mode driver that could allow the disclosure of kernel memory contents to an attacker. This vulnerability is caused when the Windows kernel-mode driver dereferences a NULL pointer. The NULL page is not typically allocated or mapped, so if the kernel dereferences a NULL pointer the usual result is a blue-screen condition. However, a blue-screen condition can be avoided if the NULL page is mapped and, because the NULL page resides in the user-mode memory address space, the attacker can copy kernel information into the NULL page and read its contents. This attack vector is not viable when NULL page mapping is disabled, which is the default state in Windows 8 and later operating systems.
* Note: This check requires an account with administrative privileges which can log into the host to scan. Absence of this condition will result in the check not being performed and a False Negative for all vulnerable hosts.

Recommendation |
Apply the appropriate patch(3034344) for your system, as listed in Microsoft Security Bulletin MS15-023 at https://technet.microsoft.com/en-us/library/security/ms15-023 -- OR -- Patches for Windows platforms are also available from the Microsoft Windows Update Web site, http://windowsupdate.microsoft.com. Windows Update detects what version of Windows you are running and offers the appropriate patch. |
