Vigil@nce - Windows: information disclosure via Kernel

May 2015 by Vigil@nce

This bulletin was written by Vigil@nce : http://vigilance.fr/offer

SYNTHESIS OF THE VULNERABILITY

local attacker can read a memory fragment of the Windows Kernel,
in order to obtain sensitive information to bypass ASLR.

Impacted products: Microsoft Windows 2012, Windows 8, Windows RT

Severity: 1/4

Creation date: 12/05/2015

DESCRIPTION OF THE VULNERABILITY

The Windows kernel uses ASLR in order to randomize memory
addresses used by programs and libraries.

However, an attacker can obtain the base address of cng.sys.

A local attacker can therefore read a memory fragment of the
Windows Kernel, in order to obtain sensitive information to bypass
ASLR.
