Detail

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

- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description: - linux: Linux kernel

Details:

It was discovered that a NULL pointer dereference existed in the keyring subsystem of the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-2647)

It was discovered that a race condition existed in the raw MIDI driver for the Linux kernel, leading to a double free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10902)

It was discovered that an integer overrun vulnerability existed in the POSIX timers implementation in the Linux kernel. A local attacker could use this to cause a denial of service. (CVE-2018-12896)

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 the YUREX USB device driver for the Linux kernel did not properly restrict user space reads or writes. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-16276)

Tetsuo Handa discovered a logic error in the TTY subsystem of the Linux kernel. A local attacker with access to pseudo terminal devices could use this to cause a denial of service. (CVE-2018-18386)

Kanda Motohiro discovered that writing extended attributes to an XFS file system in the Linux kernel in certain situations could cause an error condition to occur. A local attacker could use this to cause a denial of service. (CVE-2018-18690)

It was discovered that an integer overflow vulnerability existed in the CDROM driver of the Linux kernel. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2018-18710)

Update instructions:

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

Ubuntu 14.04 LTS:
linux-image-3.13.0-164-generic 3.13.0-164.214
linux-image-3.13.0-164-generic-lpae 3.13.0-164.214
linux-image-3.13.0-164-lowlatency 3.13.0-164.214
linux-image-3.13.0-164-powerpc-e500 3.13.0-164.214
linux-image-3.13.0-164-powerpc-e500mc 3.13.0-164.214
linux-image-3.13.0-164-powerpc-smp 3.13.0-164.214
linux-image-3.13.0-164-powerpc64-emb 3.13.0-164.214
linux-image-3.13.0-164-powerpc64-smp 3.13.0-164.214
linux-image-generic 3.13.0.164.174
linux-image-generic-lpae 3.13.0.164.174
linux-image-lowlatency 3.13.0.164.174
linux-image-powerpc-e500 3.13.0.164.174
linux-image-powerpc-e500mc 3.13.0.164.174
linux-image-powerpc-smp 3.13.0.164.174
linux-image-powerpc64-emb 3.13.0.164.174
linux-image-powerpc64-smp 3.13.0.164.174

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.
