Ubuntu 16.04 LTS : Linux kernel vulnerabilities (USN-3631-1)

high Nessus Plugin ID 109314

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3631-1 advisory.

 It was discovered that a buffer overread vulnerability existed in the keyring subsystem of the Linux kernel. A local attacker could possibly use this to expose sensitive information (kernel memory).
 (CVE-2017-13305)

 It was discovered that the DM04/QQBOX USB driver in the Linux kernel did not properly handle device attachment and warm-start. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-16538)

 Luo Quan and Wei Yang discovered that a race condition existed in the Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel when handling ioctl()s. A local attacker could use this to cause a denial of service (system deadlock). (CVE-2018-1000004)

 Wang Qize discovered that an information disclosure vulnerability existed in the SMBus driver for ACPI Embedded Controllers in the Linux kernel. A local attacker could use this to expose sensitive information (kernel pointer addresses). (CVE-2018-5750)

 discovered that a race condition existed in the Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel that could lead to a use-after-free or an out-of-bounds buffer access. A local attacker with access to /dev/snd/seq could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-7566)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
