ubuntu
Calendar Grey September 18, 2017
Dist Ubuntu Esm H88
Security updates for Ubuntu Trusty HWE kernel have been released to fix vulnerabilities in earlier versions, enhancing system security and stability
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-lts-trusty: Linux hardware enablement kernel from Trusty for Precise ESM

Details:

USN-3422-1 fixed vulnerabilities in the Linux kernel for Ubuntu 14.04

LTS. This update provides the corresponding updates for the Linux

Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for Ubuntu

12.04 LTS.

It was discovered that a buffer overflow existed in the Bluetooth stack of

the Linux kernel when handling L2CAP configuration responses. A physically

proximate attacker could use this to cause a denial of service (system

crash). (CVE-2017-1000251)

It was discovered that the asynchronous I/O (aio) subsystem of the Linux

kernel did not properly set permissions on aio memory mappings in some

situations. An attacker could use this to more easily exploit other

vulnerabilities. (CVE-2016-10044)

Baozeng Ding and Andrey Konovalov discovered a race condition in the L2TPv3

IP Encapsulation implementation in the ...

Update Instructions

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

Ubuntu 12.04 ESM:
  linux-image-3.13.0-132-generic  3.13.0-132.181~precise1
  linux-image-3.13.0-132-generic-lpae  3.13.0-132.181~precise1
  linux-image-generic-lpae-lts-trusty  3.13.0.132.122
  linux-image-generic-lts-trusty  3.13.0.132.122

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.
