Ubuntu Security Notice 2019-1 - An information leak was discovered in the handling of ICMPv6 Router Advertisement (RA) messages in the Linux kernel's IPv6 network stack. A remote attacker could exploit this flaw to cause a denial of service (excessive retries and address-generation outage), and consequently obtain sensitive information. Kees Cook discovered flaw in the Human Interface Device (HID) subsystem of the Linux kernel. A physically proximate attacker could exploit this flaw to execute arbitrary code or cause a denial of service (heap memory corruption) via a specially crafted device that provides an invalid Report ID. Various other issues were also addressed.

linux-lts-quantal vulnerabilities
============================================================================

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

- Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux-lts-quantal: Linux hardware enablement kernel from Quantal

Details:

An information leak was discovered in the handling of ICMPv6 Router
Advertisement (RA) messages in the Linux kernel's IPv6 network stack. A
remote attacker could exploit this flaw to cause a denial of service
(excessive retries and address-generation outage), and consequently obtain
sensitive information. (CVE-2013-0343)

Kees Cook discovered flaw in the Human Interface Device (HID) subsystem of
the Linux kernel. A physically proximate attacker could exploit this flaw
to execute arbitrary code or cause a denial of service (heap memory
corruption) via a specially crafted device that provides an invalid Report
ID. (CVE-2013-2888)

Kees Cook discovered flaw in the Human Interface Device (HID) subsystem
when CONFIG_HID_ZEROPLUS is enabled. A physically proximate attacker could
leverage this flaw to cause a denial of service via a specially crafted
device. (CVE-2013-2889)

Kees Cook discovered a flaw in the Human Interface Device (HID) subsystem
of the Linux kerenl when CONFIG_HID_PANTHERLORD is enabled. A physically
proximate attacker could cause a denial of service (heap out-of-bounds
write) via a specially crafted device. (CVE-2013-2892)

Kees Cook discovered another flaw in the Human Interface Device (HID)
subsystem of the Linux kernel when any of CONFIG_LOGITECH_FF,
CONFIG_LOGIG940_FF, or CONFIG_LOGIWHEELS_FF are enabled. A physcially
proximate attacker can leverage this flaw to cause a denial of service vias
a specially crafted device. (CVE-2013-2893)

Kees Cook discovered another flaw in the Human Interface Device (HID)
subsystem of the Linux kernel when CONFIG_HID_LOGITECH_DJ is enabled. A
physically proximate attacker could cause a denial of service (OOPS) or
obtain sensitive information from kernel memory via a specially crafted
device. (CVE-2013-2895)

Kees Cook discovered a vulnerability in the Linux Kernel's Human Interface
Device (HID) subsystem's support for N-Trig touch screens. A physically
proximate attacker could exploit this flaw to cause a denial of service
(OOPS) via a specially crafted device. (CVE-2013-2896)

Kees Cook discovered yet another flaw in the Human Interface Device (HID)
subsystem of the Linux kernel when CONFIG_HID_MULTITOUCH is enabled. A
physically proximate attacker could leverage this flaw to cause a denial of
service (OOPS) via a specially crafted device. (CVE-2013-2897)

Kees Cook discovered a flaw in the Human Interface Device (HID) subsystem
of the Linux kernel whe CONFIG_HID_PICOLCD is enabled. A physically
proximate attacker could exploit this flaw to cause a denial of service
(OOPS) via a specially crafted device. (CVE-2013-2899)

Alan Chester reported a flaw in the IPv6 Stream Control Transmission
Protocol (SCTP) of the Linux kernel. A remote attacker could exploit this
flaw to obtain sensitive information by sniffing network traffic.
(CVE-2013-4350)

Dmitry Vyukov reported a flaw in the Linux kernel's handling of IPv6 UDP
Fragmentation Offload (UFO) processing. A remote attacker could leverage
this flaw to cause a denial of service (system crash). (CVE-2013-4387)

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.5.0-43-generic 3.5.0-43.66~precise1

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.
