potentially exploit these to conduct cross-site scripting (XSS) attacks,
bypass sandbox restrictions, obtain sensitive information, spoof the
origin of modal alerts, bypass same origin restrictions, read
uninitialized memory, cause a denial of service via program crash or hang,
or execute arbitrary code. (CVE-2017-7753, CVE-2017-7779, CVE-2017-7780,

USN-3386-2: Linux kernel (Trusty HWE) vulnerabilities

Ubuntu Security Notice USN-3386-2

10th August, 2017

linux-lts-trusty vulnerabilities

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

  • Ubuntu 12.04 LTS

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-3386-1 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 ESM.

Andrey Konovalov discovered a race condition in the UDP Fragmentation
Offload (UFO) code in the Linux kernel. A local attacker could use this to
cause a denial of service or execute arbitrary code. (CVE-2017-1000112)

Andrey Konovalov discovered a race condition in AF_PACKET socket option
handling code in the Linux kernel. A local unprivileged attacker could use
this to cause a denial of service or possibly execute arbitrary code.
(CVE-2017-1000111)

Update instructions

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

Ubuntu 12.04 LTS:
linux-image-3.13.0-128-generic

3.13.0-128.177~precise1
linux-image-generic-lpae-lts-trusty

3.13.0-128.177~precise1

To update your system, please follow these instructions:
https://wiki.ubuntu.com/Security/Upgrades.

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.
