Ubuntu alert USN-1507-1 (linux)
========================================================================== Ubuntu Security Notice USN-1507-1 July 17, 2012 linux vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 8.04 LTS Summary: Several security issues were fixed in the kernel. Software Description: - linux: Linux kernel Details: A flaw was found in the Linux kernel's KVM (Kernel Virtual Machine) virtual cpu setup. An unprivileged local user could exploit this flaw to crash the system leading to a denial of service. (CVE-2012-1601) An error was found in the Linux kernel's IPv6 netfilter when connection tracking is enabled. A remote attacker could exploit this flaw to crash a system if it is using IPv6 with the nf_contrack_ipv6 kernel module loaded. (CVE-2012-2744) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 8.04 LTS: linux-image-2.6.24-32-386 2.6.24-32.104 linux-image-2.6.24-32-generic 2.6.24-32.104 linux-image-2.6.24-32-hppa32 2.6.24-32.104 linux-image-2.6.24-32-hppa64 2.6.24-32.104 linux-image-2.6.24-32-itanium 2.6.24-32.104 linux-image-2.6.24-32-lpia 2.6.24-32.104 linux-image-2.6.24-32-lpiacompat 2.6.24-32.104 linux-image-2.6.24-32-mckinley 2.6.24-32.104 linux-image-2.6.24-32-openvz 2.6.24-32.104 linux-image-2.6.24-32-powerpc 2.6.24-32.104 linux-image-2.6.24-32-powerpc-smp 2.6.24-32.104 linux-image-2.6.24-32-powerpc64-smp 2.6.24-32.104 linux-image-2.6.24-32-rt 2.6.24-32.104 linux-image-2.6.24-32-server 2.6.24-32.104 linux-image-2.6.24-32-sparc64 2.6.24-32.104 linux-image-2.6.24-32-sparc64-smp 2.6.24-32.104 linux-image-2.6.24-32-virtual 2.6.24-32.104 linux-image-2.6.24-32-xen 2.6.24-32.104 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.
