7.2 - USN-1995-1

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-raring: Linux hardware enablement kernel from Raring

Details:

An information leak was discovered in the Linux kernel when reading broadcast messages from the notify_policy interface of the IPSec key_socket. A local user could exploit this flaw to examine potentially sensitive information in kernel memory. (CVE-2013-2237)

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 a flaw in the Human Interface Device (HID) subsystem of the Linux kernel 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 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 an information leak in the Linux kernel's Human Interface Device (HID) subsystem when CONFIG_HID_SENSOR_HUB is enabled. A physically proximate attacker could obtain potentially sensitive information from kernel memory via a specially crafted device. (CVE-2013-2898)

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)

A flaw was discovered in how the Linux Kernel's networking stack checks scm credentials when used with namespaces. A local attacker could exploit this flaw to gain privileges. (CVE-2013-4300)

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.8.0-32-generic 3.8.0-32.47~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.
