[USN-3879-2] Linux kernel (Xenial HWE) vulnerabilities

Severity Medium
Affected Packages 17
CVEs 5
Info Packages Vulnerabilities

Several security issues were fixed in the Linux kernel.

USN-3879-1 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 LTS.

Wen Xu discovered that the ext4 file system implementation in the Linux
kernel could possibly perform an out of bounds write when updating the
journal for an inline file. An attacker could use this to construct a
malicious ext4 image that, when mounted, could cause a denial of service
(system crash). (CVE-2018-10883)

Vasily Averin and Pavel Tikhomirov discovered that the cleancache subsystem
of the Linux kernel did not properly initialize new files in some
situations. A local attacker could use this to expose sensitive
information. (CVE-2018-16862)

Wei Wu discovered that the KVM implementation in the Linux kernel did not
properly ensure that ioapics were initialized. A local attacker could use
this to cause a denial of service (system crash). (CVE-2018-19407)

Mathias Payer and Hui Peng discovered a use-after-free vulnerability in the
Advanced Linux Sound Architecture (ALSA) subsystem. A physically proximate
attacker could use this to cause a denial of service (system crash).
(CVE-2018-19824)

Hui Peng and Mathias Payer discovered that the USB subsystem in the Linux
kernel did not properly handle size checks when handling an extra USB
descriptor. A physically proximate attacker could use this to cause a
denial of service (system crash). (CVE-2018-20169)
