Ubuntu 14.04 LTS: USN-2379-1 Critical Kernel Buffer Overflows

ubuntu
Calendar Grey October 9, 2014
Scroller Ubuntu
Significant flaws in core kernel addressed in Ubuntu, impacting both safety and reliability. Immediate update necessary to resolve these concerns.
Several security issues were fixed in the kernel.

Summary

Several security issues were fixed in the kernel.

Software Description:

- linux: Linux kernel

Details:

Steven Vittitoe reported multiple stack buffer overflows in Linux kernel's

magicmouse HID driver. A physically proximate attacker could exploit this

flaw to cause a denial of service (system crash) or possibly execute

arbitrary code via specially crafted devices. (CVE-2014-3181)

Ben Hawkes reported some off by one errors for report descriptors in the

Linux kernel's HID stack. A physically proximate attacker could exploit

these flaws to cause a denial of service (out-of-bounds write) via a

specially crafted device. (CVE-2014-3184)

Several bounds check flaws allowing for buffer overflows were discovered in

the Linux kernel's Whiteheat USB serial driver. A physically proximate

attacker could exploit these flaws to cause a denial of service (system

crash) via a specially crafted device. (CVE-2014-3185)

Update Instructions

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

Ubuntu 14.04 LTS:
  linux-image-3.13.0-37-generic   3.13.0-37.64
  linux-image-3.13.0-37-generic-lpae  3.13.0-37.64
  linux-image-3.13.0-37-lowlatency  3.13.0-37.64
  linux-image-3.13.0-37-powerpc-e500  3.13.0-37.64
  linux-image-3.13.0-37-powerpc-e500mc  3.13.0-37.64
  linux-image-3.13.0-37-powerpc-smp  3.13.0-37.64
  linux-image-3.13.0-37-powerpc64-emb  3.13.0-37.64
  linux-image-3.13.0-37-powerpc64-smp  3.13.0-37.64

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. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
