Red Hat Security Advisory 2017-1484-01

Red Hat Security Advisory 2017-1484-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: A flaw was found in the way memory was being allocated on the stack for user space binaries. If heap and stack memory regions were adjacent to each other, an attacker could use this flaw to jump over the stack guard gap, cause controlled memory corruption on process stack or the adjacent memory region, and thus increase their privileges on the system. This is a kernel-side mitigation which increases the stack guard gap size from one page to 1 MiB to make successful exploitation of this issue more difficult.

Ubuntu Security Notice 3335-1 - It was discovered that the stack guard page for processes in the Linux kernel was not sufficiently large enough to prevent overlapping with the heap. An attacker could leverage this with another vulnerability to execute arbitrary code and gain administrative privileges It was discovered that a use-after-free vulnerability in the core voltage regulator driver of the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.

Red Hat Security Advisory 2017-1430-01 - Kernel-based Virtual Machine is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm package provides the user-space component for running virtual machines that use KVM. Security Fix: An out-of-bounds r/w access issue was found in QEMU's Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while copying VGA data via various bitblt functions. A privileged user inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process.

EternalBlue Exploit Analysis And Port To Microsoft Windows 10
Posted Jun 7, 2017
Authored by Sean Dillon, Dylan Davis

On April 14, 2017, the Shadow Brokers Group released the FUZZBUNCH framework, an exploitation toolkit for Microsoft Windows. The toolkit was allegedly written by the Equation Group, a highly sophisticated threat actor suspected of being tied to the United States National Security Agency (NSA). The framework included ETERNALBLUE, a remote kernel exploit originally targeting the Server Message Block (SMB) service on Microsoft Windows XP (Server 2003) and Microsoft Windows 7 (Server 2008 R2). In this paper, the RiskSense Cyber Security Research team analyzes how using wrong-sized CPU registers leads to a seemingly innocuous mathematical miscalculation. This causes a chain reaction domino effect ultimately culminating in code execution, making ETERNALBLUE one of the most complex exploits ever written. They will discuss what was necessary to port the exploit to Microsoft Windows 10, and future mitigations Microsoft has already deployed, which can prevent vulnerabilities of this class from being exploited in the future. The FUZZBUNCH version of the exploit contains an Address Space Layout Randomization (ASLR) bypass, and the Microsoft Windows 10 version required an additional Data Execution Prevention (DEP) bypass not needed in the original exploit.
