========================================================================== Ubuntu Security Notice USN-1976-1 September 30, 2013 linux vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 10.04 LTS Summary: Several security issues were fixed in the kernel. Software Description: - 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) 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 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.
