========================================================================== Ubuntu Security Notice USN-2020-1 November 08, 2013
linux-lts-raring 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-raring: Linux hardware enablement kernel from Raring
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 Aray 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)
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 12.04 LTS: linux-image-3.8.0-33-generic 3.8.0-33.48~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.
