Scroller Ubuntu
Recent updates to the Ubuntu kernel addressing OMAP4 vulnerabilities provide enhanced defense mechanisms against threats from both nearby users and remote assailants.
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:

It was discovered that the Linux kernel did not properly enforce rlimits

for file descriptors sent over UNIX domain sockets. A local attacker could

use this to cause a denial of service. (CVE-2013-4312)

Ralf Spenneberg discovered that the Aiptek Tablet USB device driver in the

Linux kernel did not properly sanity check the endpoints reported by the

device. An attacker with physical access could cause a denial of service

(system crash). (CVE-2015-7515)

Ralf Spenneberg discovered that the USB driver for Clie devices in the

Linux kernel did not properly sanity check the endpoints reported by the

device. An attacker with physical access could cause a denial of service

(system crash). (CVE-2015-7566)

Ralf Spenneberg discovered that the usbvision driver in the Linux kernel

did not properly sanity check the interfaces and endpoints reported by the

device. An atta...

Update Instructions

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

Ubuntu 12.04 LTS:
  linux-image-3.2.0-1480-omap4    3.2.0-1480.106

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.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
