Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description: - linux: Linux kernel - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-kvm: Linux kernel for cloud environments - linux-raspi2: Linux kernel for Raspberry Pi 2 - linux-snapdragon: Linux kernel for Snapdragon processors

Details:

Noam Rathaus discovered that a use-after-free vulnerability existed in the Infiniband implementation in the Linux kernel. An attacker could use this to cause a denial of service (system crash). (CVE-2018-14734)

It was discovered that an integer overflow existed in the CD-ROM driver of the Linux kernel. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2018-16658)

It was discovered that an integer overflow existed in the HID Bluetooth implementation in the Linux kernel that could lead to a buffer overwrite. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-9363)

Yves Younan discovered that the CIPSO labeling implementation in the Linux kernel did not properly handle IP header options in some situations. A remote attacker could use this to specially craft network traffic that could cause a denial of service (infinite loop). (CVE-2018-10938)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 16.04 LTS:
linux-image-4.4.0-1036-kvm 4.4.0-1036.42
linux-image-4.4.0-1070-aws 4.4.0-1070.80

linux-image-4.4.0-138-lowlatency 4.4.0-138.164
linux-image-4.4.0-138-powerpc-e500mc 4.4.0-138.164
linux-image-4.4.0-138-powerpc-smp 4.4.0-138.164

linux-image-generic-lpae 4.4.0.138.144
linux-image-kvm 4.4.0.1036.35
linux-image-lowlatency 4.4.0.138.144
linux-image-powerpc-e500mc 4.4.0.138.144
linux-image-powerpc-smp 4.4.0.138.144
linux-image-powerpc64-emb 4.4.0.138.144
linux-image-powerpc64-smp 4.4.0.138.144
linux-image-raspi2 4.4.0.1099.99
linux-image-snapdragon 4.4.0.1103.95

After a standard system update you need to reboot your computer to make all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
