USN-1976-1: Linux kernel vulnerabilities

30 September 2013

linux vulnerabilities

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

  • Ubuntu 10.04 LTS


Several security issues were fixed in the kernel.

Software Description

  • linux - Linux kernel


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 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)

Update instructions

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

Ubuntu 10.04 LTS
linux-image-2.6.32-52-386 - 2.6.32-52.114
linux-image-2.6.32-52-generic - 2.6.32-52.114
linux-image-2.6.32-52-generic-pae - 2.6.32-52.114
linux-image-2.6.32-52-ia64 - 2.6.32-52.114
linux-image-2.6.32-52-lpia - 2.6.32-52.114
linux-image-2.6.32-52-powerpc - 2.6.32-52.114
linux-image-2.6.32-52-powerpc-smp - 2.6.32-52.114
linux-image-2.6.32-52-powerpc64-smp - 2.6.32-52.114
linux-image-2.6.32-52-preempt - 2.6.32-52.114
linux-image-2.6.32-52-server - 2.6.32-52.114
linux-image-2.6.32-52-sparc64 - 2.6.32-52.114
linux-image-2.6.32-52-sparc64-smp - 2.6.32-52.114
linux-image-2.6.32-52-versatile - 2.6.32-52.114
linux-image-2.6.32-52-virtual - 2.6.32-52.114

To update your system, please follow these instructions:

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.
