Ubuntu Security Notice 3378-2 - USN-3378-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS. Fan Wu and Shixiong Zhao discovered a race condition between inotify events and vfs rename operations in the Linux kernel. An unprivileged local attacker could use this to cause a denial of service or execute arbitrary code. Various other issues were also addressed.

linux-lts-xenial vulnerabilities
===========================================================================

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

- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty

Details:

USN-3378-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04
LTS. This update provides the corresponding updates for the Linux
Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu
14.04 LTS.

Fan Wu and Shixiong Zhao discovered a race condition between inotify events
and vfs rename operations in the Linux kernel. An unprivileged local
attacker could use this to cause a denial of service (system crash) or
execute arbitrary code. (CVE-2017-7533)

It was discovered that the Linux kernel did not properly restrict
RLIMIT_STACK size. A local attacker could use this in conjunction with
another vulnerability to possibly execute arbitrary code.
(CVE-2017-1000365)

=E6=9D=8E=E5=BC=BA discovered that the Virtio GPU driver in the Linux kernel did not
properly free memory in some situations. A local attacker could use this to
cause a denial of service (memory consumption). (CVE-2017-10810)

=E7=9F=B3=E7=A3=8A discovered that the RxRPC Kerberos 5 ticket handling code in the
Linux kernel did not properly verify metadata. A remote attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2017-7482)

Update instructions:

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

Ubuntu 14.04 LTS:
linux-image-4.4.0-89-generic 4.4.0-89.112~14.04.1
linux-image-4.4.0-89-generic-lpae 4.4.0-89.112~14.04.1
linux-image-4.4.0-89-lowlatency 4.4.0-89.112~14.04.1
linux-image-4.4.0-89-powerpc-e500mc 4.4.0-89.112~14.04.1
linux-image-4.4.0-89-powerpc-smp 4.4.0-89.112~14.04.1
linux-image-4.4.0-89-powerpc64-emb 4.4.0-89.112~14.04.1
linux-image-4.4.0-89-powerpc64-smp 4.4.0-89.112~14.04.1
linux-image-generic-lpae-lts-xenial 4.4.0.89.74
linux-image-generic-lts-xenial 4.4.0.89.74
linux-image-lowlatency-lts-xenial 4.4.0.89.74
linux-image-powerpc-e500mc-lts-xenial 4.4.0.89.74
linux-image-powerpc-smp-lts-xenial 4.4.0.89.74
linux-image-powerpc64-emb-lts-xenial 4.4.0.89.74
linux-image-powerpc64-smp-lts-xenial 4.4.0.89.74

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.
