USN-2015-1: Linux kernel vulnerabilities
8 November 2013
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.04 LTS
Several security issues were fixed in the kernel.
- linux - Linux kernel
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 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)
A flaw was discovered in the Linux kernel’s dm snapshot facility. A remote authenticated user could exploit this flaw to obtain sensitive information or modify/corrupt data. (CVE-2013-4299)
The problem can be corrected by updating your system to the following package versions:
- Ubuntu 10.04 LTS
- linux-image-2.6.32-53-386 - 2.6.32-53.115
- linux-image-2.6.32-53-generic - 2.6.32-53.115
- linux-image-2.6.32-53-generic-pae - 2.6.32-53.115
- linux-image-2.6.32-53-ia64 - 2.6.32-53.115
- linux-image-2.6.32-53-lpia - 2.6.32-53.115
- linux-image-2.6.32-53-powerpc - 2.6.32-53.115
- linux-image-2.6.32-53-powerpc-smp - 2.6.32-53.115
- linux-image-2.6.32-53-powerpc64-smp - 2.6.32-53.115
- linux-image-2.6.32-53-preempt - 2.6.32-53.115
- linux-image-2.6.32-53-server - 2.6.32-53.115
- linux-image-2.6.32-53-sparc64 - 2.6.32-53.115
- linux-image-2.6.32-53-sparc64-smp - 2.6.32-53.115
- linux-image-2.6.32-53-versatile - 2.6.32-53.115
- linux-image-2.6.32-53-virtual - 2.6.32-53.115
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
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.
