CVE-2013-2094 Mitigation Fix

This script provides an easy mechnism for generating portable SystemTap modules that can be loaded with systemtap-runtime to mitigate the vulnerability described in CVE-2013-2094.

This toolset is aimed towards RHEL6, but will likely work without modification on other Enterprise Linux based distros.

Instructions

Ensure you have the debuginfo repository for your distro installed.

Run the build for the kernel version you wish to target

./build.sh $(uname -r)

You'll be provided with a kernel module that looks something like:

cve_2013_2094__2_6_32_358_6_1_el6_x86_64.ko

To put this into affect, you must distribute the module to the target systems, and run the following command:

staprun -L cve_2013_2094__2_6_32_358_6_1_el6_x86_64.ko

IMPORTANT NOTE: You must reload this module after every restart.
