the in depth technical details

TL;DR; sigalarm handler calls syslog which isn't safe to call from a signal handler context.

Their example exploit needed about 10k attempts to get a remote shell so it's not fast or quiet, but a neat find regardless

Yeah, the 20th least polluting country is near 1000x worse than the estimated CO2 footprint in the article

You're right... The "more than 20 countries" thing, is about 1000x away from the real number too, so I guess they dropped a "kilo" somewhere and somehow didn't react to getting an obviously absurd result

This is hugely incorrect

... equivalent to 281,315 metric tons of CO2. This is roughly the same quantity of emissions that 75 coal-fired power plants produce in a year, and it exceeds the annual emissions of 20 individual countries and territories.

A single medium sized (1MW) coal power plant outputs about 6.3 million metric tons CO2 per year, so the comparison is three magnitudes off

I wouldn't trust any other numbers from that site without verification
