Ubuntu 16.04 LTS : Linux kernel (AWS, GKE) vulnerabilities (USN-3364-3)

medium Nessus Plugin ID 101973

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-3364-3 advisory.

 It was discovered that the Linux kernel did not properly initialize a Wake- on-Lan data structure. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2014-9900)

 It was discovered that the Linux kernel did not properly restrict access to /proc/iomem. A local attacker could use this to expose sensitive information. (CVE-2015-8944)

 Alexander Potapenko discovered a race condition in the Advanced Linux Sound Architecture (ALSA) subsystem in the Linux kernel. A local attacker could use this to expose sensitive information (kernel memory).
 (CVE-2017-1000380)

 Li Qiang discovered that the DRM driver for VMware Virtual GPUs in the Linux kernel did not properly validate some ioctl arguments. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-7346)

 Jann Horn discovered that bpf in Linux kernel does not restrict the output of the print_bpf_insn function.
 A local attacker could use this to obtain sensitive address information. (CVE-2017-9150)

 Murray McAllister discovered that the DRM driver for VMware Virtual GPUs in the Linux kernel did not properly initialize memory. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2017-9605)

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.
