Scroller Ubuntu
Multiple vulnerabilities addressed in the Linux kernel for OMAP4 on Ubuntu, focusing on the mitigation of unauthorized access exploits.
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:

Vasily Kulikov reported a flaw in the Linux kernel's implementation of

ptrace. An unprivileged local user could exploit this flaw to obtain

sensitive information from kernel memory. (CVE-2013-2929)

A flaw in the handling of memory regions of the kernel virtual machine

(KVM) subsystem was discovered. A local user with the ability to assign a

device could exploit this flaw to cause a denial of service (memory

consumption). (CVE-2013-4592)

Nico Golde and Fabian Yamaguchi reported a flaw in the Linux kernel's

debugfs filesystem. An administrative local user could exploit this flaw to

cause a denial of service (OOPS). (CVE-2013-6378)

Nico Golde and Fabian Yamaguchi reported a flaw in the driver for Adaptec

AACRAID scsi raid devices in the Linux kernel. A local user could use this

flaw to cause a denial of service or possibly other unspeci...

Update Instructions

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

Ubuntu 13.10:
  linux-image-3.5.0-238-omap4     3.5.0-238.54

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.
