Ubuntu 14.04 LTS : linux-lts-xenial vulnerabilities (USN-3485-2)

High Nessus Plugin ID 104717

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

USN-3485-1 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.

It was discovered that a race condition existed in the ALSA subsystem of the Linux kernel when creating and deleting a port via ioctl(). A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-15265)

Eric Biggers discovered that the key management subsystem in the Linux kernel did not properly restrict adding a key that already exists but is uninstantiated. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
(CVE-2017-15299)

It was discovered that a race condition existed in the packet fanout implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-15649)

Eric Biggers discovered a race condition in the key management subsystem of the Linux kernel around keys in a negative state. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-15951)

Andrey Konovalov discovered a use-after-free vulnerability in the USB serial console driver in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-16525)

Andrey Konovalov discovered that the Ultra Wide Band driver in the Linux kernel did not properly check for an error condition. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
(CVE-2017-16526)

Andrey Konovalov discovered that the ALSA subsystem in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-16527)

Andrey Konovalov discovered that the ALSA subsystem in the Linux kernel did not properly validate USB audio buffer descriptors. A physically proximate attacker could use this cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-16529)

Andrey Konovalov discovered that the USB unattached storage driver in the Linux kernel contained out-of-bounds error when handling alternative settings. A physically proximate attacker could use to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-16530)

Andrey Konovalov discovered that the USB subsystem in the Linux kernel did not properly validate USB interface association descriptors. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2017-16531)

Andrey Konovalov discovered that the USB subsystem in the Linux kernel did not properly validate USB HID descriptors. A physically proximate attacker could use this to cause a denial of service (system crash).
(CVE-2017-16533)

Andrey Konovalov discovered that the USB subsystem in the Linux kernel did not properly validate CDC metadata. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-16534)

Andrey Konovalov discovered that the USB subsystem in the Linux kernel did not properly validate USB BOS metadata. A physically proximate attacker could use this to cause a denial of service (system crash).
(CVE-2017-16535).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
