Ubuntu Security Notice USN-3018-1
June 27, 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:

Jesse Hertz and Tim Newsham discovered that the Linux netfilter
implementation did not correctly perform validation when handling 32 bit
compatibility IPT_SO_SET_REPLACE events on 64 bit platforms. A local
unprivileged attacker could use this to cause a denial of service (system
crash) or execute arbitrary code with administrative privileges.
(CVE-2016-4997)

Kangjie Lu discovered an information leak in the core USB implementation in
the Linux kernel. A local attacker could use this to obtain potentially
sensitive information from kernel memory. (CVE-2016-4482)

Jann Horn discovered that the InfiniBand interfaces within the Linux kernel
could be coerced into overwriting kernel memory. A local unprivileged
attacker could use this to possibly gain administrative privileges on
systems where InifiniBand related kernel modules are loaded.
(CVE-2016-4565)

Kangjie Lu discovered an information leak in the timer handling
implementation in the Advanced Linux Sound Architecture (ALSA) subsystem of
the Linux kernel. A local attacker could use this to obtain potentially
sensitive information from kernel memory. (CVE-2016-4569, CVE-2016-4578)

Kangjie Lu discovered an information leak in the X.25 Call Request handling
in the Linux kernel. A local attacker could use this to obtain potentially
sensitive information from kernel memory. (CVE-2016-4580)

It was discovered that an information leak exists in the Rock Ridge
implementation in the Linux kernel. A local attacker who is able to mount a
malicious iso9660 file system image could exploit this flaw to obtain
potentially sensitive information from kernel memory. (CVE-2016-4913)

Jesse Hertz and Tim Newsham discovered that the Linux netfilter
implementation did not correctly perform validation when handling
IPT_SO_SET_REPLACE events. A local unprivileged attacker could use this to
cause a denial of service (system crash) or obtain potentially sensitive
information from kernel memory. (CVE-2016-4998)

Update instructions:

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

Ubuntu 14.04 LTS:
  linux-image-3.13.0-91-generic   3.13.0-91.138
  linux-image-3.13.0-91-generic-lpae  3.13.0-91.138
  linux-image-3.13.0-91-lowlatency  3.13.0-91.138
  linux-image-3.13.0-91-powerpc-e500  3.13.0-91.138
  linux-image-3.13.0-91-powerpc-e500mc  3.13.0-91.138
  linux-image-3.13.0-91-powerpc-smp  3.13.0-91.138
  linux-image-3.13.0-91-powerpc64-emb  3.13.0-91.138
  linux-image-3.13.0-91-powerpc64-smp  3.13.0-91.138

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.
