[USN-4095-2] Linux kernel (Xenial HWE) vulnerabilities

Severity Medium

Info Packages Vulnerabilities

Several security issues were fixed in the Linux kernel.

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 (HWE) 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. (CVE-2018-5383)

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 (system crash) or possibly execute arbitrary
code. (CVE-2019-10126)

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 (kernel
memory). (CVE-2019-1125)

It was discovered that the ext4 file system implementation in the Linux
kernel did not properly zero out memory in some situations. A local
attacker could use this to expose sensitive information (kernel memory).
(CVE-2019-11833)

It was discovered that the PowerPC dlpar implementation in the Linux kernel
did not properly check for allocation errors in some situations. A local
attacker could possibly use this to cause a denial of service (system
crash). (CVE-2019-12614)

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. (CVE-2019-2054)

It was discovered that the Marvell Wireless LAN device driver in the Linux
kernel did not properly validate the BSS descriptor. A local attacker could
possibly use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2019-3846)
