Ubuntu Security Notice USN-2179-1
April 26, 2014

linux vulnerabilities
==========================================================================

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

- Ubuntu 13.10

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux: Linux kernel

Details:

A flaw was discovered in the Kernel Virtual Machine (KVM) subsystem of the
Linux kernel. A guest OS user could exploit this flaw to execute arbitrary
code on the host OS. (CVE-2014-0049)

Al Viro discovered an error in how CIFS in the Linux kernel handles
uncached write operations. An unprivileged local user could exploit this
flaw to cause a denial of service (system crash), obtain sensitive
information from kernel memory, or possibly gain privileges.
(CVE-2014-0069)

Update instructions:

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

Ubuntu 13.10:
linux-image-3.11.0-20-generic 3.11.0-20.34
linux-image-3.11.0-20-generic-lpae 3.11.0-20.34

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.

linux-ti-omap4 vulnerabilities
==========================================================================

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

- Ubuntu 12.10

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux-ti-omap4: Linux kernel for OMAP4

Details:

A flaw was discovered in the Kernel Virtual Machine (KVM) subsystem of the
Linux kernel. A guest OS user could exploit this flaw to execute arbitrary
code on the host OS. (CVE-2014-0049)

Al Viro discovered an error in how CIFS in the Linux kernel handles
uncached write operations. An unprivileged local user could exploit this
flaw to cause a denial of service (system crash), obtain sensitive
information from kernel memory, or possibly gain privileges.
(CVE-2014-0069)

Update instructions:

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

Ubuntu 12.10:
linux-image-3.5.0-241-omap4 3.5.0-241.57

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
