Details

Pengfei Wang discovered that the Turtle Beach MultiSound audio device
driver in the Linux kernel contained race conditions when fetching from the
ring-buffer, leading to an out-of-bounds access. A local attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2017-9986)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:

  • Ethernet bonding driver;
  • PCI subsystem;
  • SCSI subsystem;
  • Tracing infrastructure;
  • B.A.T.M.A.N. meshing protocol;
  • IUCV driver

Update instructions

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

Learn more about how to get the fixes.

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.

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

Ubuntu Release Package Version
14.04 LTS trusty linux-image-3.13.0-220-generic –  3.13.0-220.271  
linux-image-3.13.0-220-lowlatency –  3.13.0-220.271  
linux-image-generic –  3.13.0.220.230  
linux-image-generic-lts-trusty –  3.13.0.220.230  
linux-image-lowlatency –  3.13.0.220.230  
linux-image-server –  3.13.0.220.230  
linux-image-virtual –  3.13.0.220.230  

Reduce your security exposure

Ubuntu Pro provides ten-year security coverage to 25,000+ packages in Main and Universe repositories, and it is free for up to five machines.
