USN-2023-1: Linux kernel vulnerabilities
8 November 2013
Several security issues were fixed in the kernel.

Packages
- linux - Linux kernel
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)
Dan Carpenter discovered an information leak in the HP Smart Array and
Compaq SMART2 disk-array driver in the Linux kernel. A local user could
exploit this flaw to obtain sensitive information from kernel memory.
(CVE-2013-2147)
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 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 a flaw in the Human Interface Device (HID) subsystem
of the Linux kernel when CONFIG_HID_LENOVO_TPKBD is enabled. A physically
proximate attacker could exploit this flaw to cause a denial of service via
a specially crafted device. (CVE-2013-2894)
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 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)
Miroslav Vadkerti discovered a flaw in how the permissions for network
sysctls are handled in the Linux kernel. An unprivileged local user could
exploit this flaw to have privileged access to files in /proc/sys/net/.
(CVE-2013-4270)
Wannes Rombouts reported a vulnerability in the networking tuntap interface
of the Linux kernel. A local user with the CAP_NET_ADMIN capability could
leverage this flaw to gain full admin privileges. (CVE-2013-4343)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 13.04
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.
