Scroller Ubuntu
Numerous vulnerabilities in Ubuntu's Linux kernel addressed; consult advisory for comprehensive information on patches and security risks.
Several security issues were fixed in the kernel.

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 13.10:
  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
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.
