Summary: This security update resolves four privately reported vulnerabilities in Microsoft Windows. The most severe of these vulnerabilities could allow security feature bypass 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.

Title: Microsoft windows kernel memory disclosure vulnerability - CVE-2015-0094 (MS15-023)
Description: The kernel-mode drivers in Microsoft Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1 do not properly restrict the availability of address information during a function call, which makes it easier for local users to bypass the ASLR protection mechanism via a crafted application, aka "Microsoft Windows Kernel Memory Disclosure Vulnerability."

Title: Microsoft windows kernel memory disclosure vulnerability - CVE-2015-0077 (MS15-023)
Description: The kernel-mode drivers in Microsoft Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1 do not properly initialize function buffers, which allows local users to obtain sensitive information from kernel memory, and possibly bypass the ASLR protection mechanism, via a crafted application, aka "Microsoft Windows Kernel Memory Disclosure Vulnerability."
