Ubuntu Security Notice USN-4095-2
Posted Aug 14, 2019
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 4095-2 - USN-4095-1 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 ESM. Eli Biham and Lior Neumann discovered that the Bluetooth implementation in the Linux kernel did not properly validate elliptic curve parameters during Diffie-Hellman key exchange in some situations. An attacker could use this to expose sensitive information. Various other issues were also addressed.

Ubuntu Security Notice 4093-1 - It was discovered that a heap buffer overflow existed in the Marvell Wireless LAN device driver for the Linux kernel. An attacker could use this to cause a denial of service or possibly execute arbitrary code. Andrei Vlad Lutas and Dan Lutas discovered that some x86 processors incorrectly handle SWAPGS instructions during speculative execution. A local attacker could use this to expose sensitive information. Various other issues were also addressed.

Kernel Live Patch Security Notice LSN-0053-1

Authored by Benjamin M. Romer

Vasiliy Kulikov discovered that the Bluetooth stack did not correctly check that device name strings were NULL terminated. A local attacker could exploit this to crash the system, leading to a denial of service, or leak contents of kernel stack memory, leading to a loss of privacy. It was discovered that the Linux kernel on ARM processors allowed a tracing process to modify a syscall after a seccomp decision had been made on that syscall. A local attacker could possibly use this to bypass seccomp restrictions. Various other issues were also addressed.
