Ubuntu Security Notice USN-3291-3
Posted May 18, 2017
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 3291-3 - USN-3291-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS. Dmitry Vyukov discovered that the generic SCSI subsystem in the Linux kernel contained a stack-based buffer overflow. A local attacker with access to an sg device could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.

MS17-010 EternalBlue SMB Remote Windows Kernel Pool Corruption
Posted May 17, 2017
Authored by Sean Dillon, Shadow Brokers, Dylan Davis, Equation Group | Site metasploit.com

This Metasploit module is a port of the Equation Group ETERNALBLUE exploit, part of the FuzzBunch toolkit released by Shadow Brokers. There is a buffer overflow memmove operation in Srv!SrvOs2FeaToNt. The size is calculated in Srv!SrvOs2FeaListSizeToNt, with mathematical error where a DWORD is subtracted into a WORD. The kernel pool is groomed so that overflow is well laid-out to overwrite an SMBv1 buffer. Actual RIP hijack is later completed in srvnet!SrvNetWskReceiveComplete. This exploit, like the original may not trigger 100% of the time, and should be run continuously until triggered. It seems like the pool will get hot streaks and need a cool down period before the shells rain in again.

Kernel Live Patch Security Notice LSN-0022-1
Posted May 17, 2017
Authored by Benjamin M. Romer

It was discovered that a use-after-free flaw existed in the filesystem encryption subsystem in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). Andreas Gruenbacher and Jan Kara discovered that the filesystem implementation in the Linux kernel did not clear the setgid bit during a setxattr call. A local attacker could use this to possibly elevate group privileges.

Red Hat Security Advisory 2017-1232-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: A race condition flaw was found in the N_HLDC Linux kernel driver when accessing n_hdlc.tbuf list that can lead to double free. A local, unprivileged user able to set the HDLC line discipline on the tty device could use this flaw to increase their privileges on the system.

Microsoft Windows Kernel bind() Out-Of-Bounds Read
Posted May 16, 2017
Authored by Google Security Research, mjurczyk

Two related bugs have been discovered in the Microsoft Windows kernel code responsible for implementing the bind() socket function, specifically in the afd!AfdBind and tcpip!TcpBindEndpoint routines. They both can lead to reading beyond the allocated pool-based buffer memory area, potentially allowing user-mode applications to disclose kernel-mode secrets. They can also be exploited to trigger a blue screen of death and therefore a denial of service condition.

Red Hat Security Advisory 2017-1206-01 - 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: A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support; the issue could occur when a VNC client attempted to update its display after a VGA operation is performed by a guest. A privileged user/process 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.

Red Hat Security Advisory 2017-1209-01 - The rhev-hypervisor package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine hypervisor. It includes everything necessary to run and manage virtual machines: A subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent. Security Fix: A use-after-free flaw was found in the way the Linux kernel's Datagram Congestion Control Protocol implementation freed SKB resources for a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option is set on the socket. A local, unprivileged user could use this flaw to alter the kernel memory, allowing them to escalate their privileges on the system.
