This Metasploit module attempts to gain root privileges on Linux systems by abusing UDP Fragmentation Offload (UFO). This exploit targets only systems using Ubuntu (Trusty / Xenial) kernels 4.4.0-21 <= 4.4.0-89 and 4.8.0-34 <= 4.8.0-58, including Linux distros based on Ubuntu, such as Linux Mint. The target system must have unprivileged user namespaces enabled and SMAP disabled. Bypasses for SMEP and KASLR are included. Failed exploitation may crash the kernel. This Metasploit module has been tested successfully on various Ubuntu and Linux Mint systems, including: Ubuntu 14.04.5 4.4.0-31-generic x64 Desktop; Ubuntu 16.04 4.8.0-53-generic; Linux Mint 17.3 4.4.0-89-generic; Linux Mint 18 4.8.0-58-generic
365cc8e31e8378f416a359810066fcdaRed Hat Security Advisory 2017-3200-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets are implemented in the Linux kernel networking subsystem handling synchronization. A local user able to open a raw packet socket could use this flaw to elevate their privileges on the system.
00763be259ce14f050bd1ac8fa6dfbd5Red Hat Security Advisory 2017-2931-01 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix: Out-of-bounds kernel heap access vulnerability was found in xfrm, kernel's IP framework for transforming packets. An error dealing with netlink messages from an unprivileged user leads to arbitrary read/write and privilege escalation.
