Descriptions
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."
Los controladores de modo de kernel en Microsoft Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 y R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold y R2, y Windows RT Gold y 8.1 no restringe correctamente la disponibilidad de la información de direcciones durante la llamada a una función, lo que facilita a usuarios locales evadir el mecanismo de protección ASLR a través de una aplicación manipulada, también conocido como 'vulnerabilidad de la divulgación de la memoria del kernel de Microsoft Windows.'
This vulnerability allows local attackers to leak sensitive information on vulnerable installations of Microsoft Windows. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the handling of NtUserfnINOUTNCCALCSIZE function. The issue lies in the failure to sanitize a buffer before calling a userland function resulting in the leak of an address on the kernel trap frame. An attacker can leverage this in concert with another vulnerability to achieve code execution at SYSTEM.
