Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.10

Summary:

Several security issues were fixed in the kernel.

Software Description: - linux: Linux kernel

Details:

It was discovered that hypervkvpd, which is distributed in the Linux kernel, was not correctly validating the origin on Netlink messages. An untrusted local user can cause a denial of service of Linux guests in Hyper-V virtualization environments. (CVE-2012-2669)

Dmitry Monakhov reported a race condition flaw the Linux ext4 filesystem that can expose stale data. An unprivileged user could exploit this flaw to cause an information leak. (CVE-2012-4508)

Florian Weimer discovered that hypervkvpd, which is distributed in the Linux kernel, was not correctly validating source addresses of netlink packets. An untrusted local user can cause a denial of service by causing hypervkvpd to exit. (CVE-2012-5532)

Andrew Cooper of Citrix reported a Xen stack corruption in the Linux kernel. An unprivileged user in a 32bit PVOPS guest can cause the guest kernel to crash, or operate erroneously. (CVE-2013-0190)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 11.10:
linux-image-3.0.0-31-generic 3.0.0-31.48
linux-image-3.0.0-31-generic-pae 3.0.0-31.48
linux-image-3.0.0-31-omap 3.0.0-31.48
linux-image-3.0.0-31-powerpc 3.0.0-31.48
linux-image-3.0.0-31-powerpc-smp 3.0.0-31.48
linux-image-3.0.0-31-powerpc64-smp 3.0.0-31.48
linux-image-3.0.0-31-server 3.0.0-31.48
linux-image-3.0.0-31-virtual 3.0.0-31.48

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.
