"Drain" files while they are processed to reduce free disk space requirements
// Sometimes you have a large file on a small disk and would like to "transform"
// it in some way: for example, by decompressing it. However, you might not have
// enough space on disk to keep both the the compressed file and the
// decompressed results. If the process can be done in a streaming fashion, it
// would be nice if the file could be "drained"; that is, the file would be
// sequentially deleted as it is consumed. At the start you'd have 100% of the
// original file, somewhere in the middle you'd have about half of the original
// file and half of your output, and by the end the original file will be gone
// and you'll be left with just the results. If you do it this way, you might
// be able to do the entire operation without extra space!

Some quick notes about the CVE-2023-3079(V8 type confusion), no PoC yet.

Official patch: https://chromium-review.googlesource.com/c/v8/v8/+/4584248

Patch come from KeyedStoreIC::StoreElementHandler(), it returns fast path code(Turbofan builtin) for keyed store depends on "receiver_map" and "store_mode". Based on the content of this function is all about element STORE, I personally believe that this is an OOB writes vulnerability.

If we divide the PoC exploration into two parts based on this func, they are:

Guide on how to remap Keyboard keys on macOS

Guide on how to remap Keyboard keys on macOS

Update 17.10.2024: macOS 15 no longer requires root privileges for hidutil, you need to add hidutil and Terminal to 'Input Monitoring' in Settings/Privacy & Security tab.

Update 13.04.2024: On macOS 14.2 hidutil requires root privileges.

If you have a mac with an INT (ISO) keyboard you might want to change the ± key to ~. During my research I found that the information on this topic is not at all centralized. I prefer this option because it does not involve installing new software.

With macOS 10.12 Sierra Apple introduced hidutil as a tool to remap keyboard keys. See TN2450.
