/*
Bug: typecasting uint8_t* ab.backingStore to uint16_t* ta.mem while converting ArrayBuffer to Uint16Array,
but not reducing length, allows oob r/w.

Exploit: create ArrayBuffer of same size as JSObject, so that they come consecutively in memory,
use oob r/w to overwrite JSObject metadata, construct arbitrary r/w primitives, overwrite
Array constructor with system, JSState with "/bin/sh"
*/

test = new ArrayBuffer(0x70);

# The script will calculate the value of gp register base on the code in entry(), then apply the value to all the functions
# This only work in the `RV64I` language though, since other language like `RV64GC` won't set the gp register in entry()

Enable X11 forward to load images from remote server on MacOS Mojave

Steps

1. Install Xquartz to get X11 support on MacOS. You can google Xquartz and download it from its official site, or install using HomeBrew.

   brew cask install xquartz

2. Launch Xquartz. Go to Preference -> Security, click the box Allow connections from clients. NOTE: You have to lauch Xquartz with Allow connections from clients enable everytime you want to ssh to remote server with X11 forwarding support.

Ok, I geeked out, and this is probably more information than you need. But it completely answers the question. Sorry. ☺

Locally, I'm at this commit:

$ git show
commit d6cd1e2bd19e03a81132a23b2025920577f84e37
Author: jnthn <[email protected]>
Date:   Sun Apr 15 16:35:03 2012 +0200

When I added FIRST/NEXT/LAST, it was idiomatic but not quite so fast. This makes it faster. Another little bit of masak++'s program.
