Ubuntu Security Notice USN-3127-1
November 11, 2016

linux vulnerabilities
==========================================================================

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

- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux: Linux kernel

Details:

It was discovered that the compression handling code in the Advanced Linux
Sound Architecture (ALSA) subsystem in the Linux kernel did not properly
check for an integer overflow. A local attacker could use this to cause a
denial of service (system crash). (CVE-2014-9904)

Kirill A. Shutemov discovered that memory manager in the Linux kernel did
not properly handle anonymous pages. A local attacker could use this to
cause a denial of service or possibly gain administrative privileges.
(CVE-2015-3288)

Vitaly Kuznetsov discovered that the Linux kernel did not properly suppress
hugetlbfs support in X86 paravirtualized guests. An attacker in the guest
OS could cause a denial of service (guest system crash). (CVE-2016-3961)

Ondrej Kozina discovered that the keyring interface in the Linux kernel
contained a buffer overflow when displaying timeout events via the
/proc/keys interface. A local attacker could use this to cause a denial of
service (system crash). (CVE-2016-7042)

Update instructions:

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

Ubuntu 14.04 LTS:
linux-image-3.13.0-101-generic 3.13.0-101.148
linux-image-3.13.0-101-generic-lpae 3.13.0-101.148
linux-image-3.13.0-101-lowlatency 3.13.0-101.148
linux-image-3.13.0-101-powerpc-e500 3.13.0-101.148
linux-image-3.13.0-101-powerpc-e500mc 3.13.0-101.148
linux-image-3.13.0-101-powerpc-smp 3.13.0-101.148
linux-image-3.13.0-101-powerpc64-emb 3.13.0-101.148
linux-image-3.13.0-101-powerpc64-smp 3.13.0-101.148
linux-image-generic 3.13.0.101.109
linux-image-generic-lpae 3.13.0.101.109
linux-image-lowlatency 3.13.0.101.109
linux-image-powerpc-e500 3.13.0.101.109
linux-image-powerpc-e500mc 3.13.0.101.109
linux-image-powerpc-smp 3.13.0.101.109
linux-image-powerpc64-emb 3.13.0.101.109
linux-image-powerpc64-smp 3.13.0.101.109
linux-image-virtual 3.13.0.101.109

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.
