========================================================================== Ubuntu Security Notice USN-1473-1 June 13, 2012
linux 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: Linux kernel
Details:
A flaw was discovered in the Linux kernel's KVM (kernel virtual machine). An administrative user in the guest OS could leverage this flaw to cause a denial of service in the host OS. (CVE-2012-2121)
Schacher Raindel discovered a flaw in the Linux kernel's memory handling when hugetlb is enabled. An unprivileged local attacker could exploit this flaw to cause a denial of service and potentially gain higher privileges. (CVE-2012-2133)
Stephan Mueller reported a flaw in the Linux kernel's dl2k network driver's handling of ioctls. An unprivileged local user could leverage this flaw to cause a denial of service. (CVE-2012-2313)
Timo Warns reported multiple flaws in the Linux kernel's hfsplus filesystem. An unprivileged local user could exploit these flaws to gain root system priviliges. (CVE-2012-2319)
Xi Wang discovered a flaw in the Linux kernel's i915 graphics driver handling of cliprect on 32 bit systems. An unprivileged local attacker could leverage this flaw to cause a denial of service or potentially gain root privileges. (CVE-2012-2383)
Xi Wang discovered a flaw in the Linux kernel's i915 graphics driver handling of buffer_count on 32 bit systems. An unprivileged local attacker could leverage this flaw to cause a denial of service or potentially gain root privileges. (CVE-2012-2384)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04 LTS: linux-image-3.2.0-25-generic 3.2.0-25.40 linux-image-3.2.0-25-generic-pae 3.2.0-25.40 linux-image-3.2.0-25-highbank 3.2.0-25.40 linux-image-3.2.0-25-omap 3.2.0-25.40 linux-image-3.2.0-25-powerpc-smp 3.2.0-25.40 linux-image-3.2.0-25-powerpc64-smp 3.2.0-25.40 linux-image-3.2.0-25-virtual 3.2.0-25.40
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.
