Quite a novel attack originally reported on Reddit.

Basically, it was possible to use a bug in the wallet software to send multiple outputs to the same stealth wallet, potentially allowing an attacker to cheaply burn a large amount of someone else's tokens, on account of the wallet simplying ignoring the issue.

This has now been fixed. Great work from the Monero team.

The article didn't really specify what a stealth wallet is. Can you elaborate? Are there different types of wallets on the monero network? Is a stealth wallet just a public private key pair derived address that you can somehow use to impersonate another account?
