Patching CVE-2015-1474 -- Remotely exploitable graphics buffer overflow on my Nexus device (N5 5.0.1)

This is a brief guide on how I patched the CVE-2015-1474 for my Nexus 5 - 5.0.1. This involes downloading and building AOSP with the patch for the vuln applied. I have attached a pre-built patched version of libui.so for the Nexus5 5.0.1 in the case you are too lazy to build it yourself (and you trust me).

Building patched libui for your nexus device

repo init -u https://android.googlesource.com/platform/manifest -b android-5.0.1_r1
repo sync -j16

cd frameworks/native

For applications targeting Android >= 5.0, you can enumerate the methods available from inside javascript. "Enumeration of methods will be enabled for applications targeting API levels newer than KitKat (to preserve compatibility with older apps)."
