Retbleed leaks password data
Intel and AMD are vulnerable to a newly discovered speculative execution attack that can covertly leak password data and other sensitive material.
According to Ars Technica, ETH Zurich named their attack Retbleed because it exploits a software defense known as retpoline, which was introduced in 2018 to mitigate the harmful effects of speculative execution attacks.
For those not in the know another speculative execution attack, also known as Spectre, exploit the fact that when modern CPUs encounter a direct or indirect instruction branch, they predict the address for the next instruction they're about to receive and automatically execute it before the prediction is confirmed.
