The Apache Software Foundation has announced a denial-of-service vulnerability that affects all versions of the ubiquitous Apache web server, leaving up to 65% of all websites vulnerable.
A denial of service attack works by flooding a server with information and making it so busy that it locks-up and becomes useless. Normally an attacker would have to martial some serious horsepower to overwhelm a big website but this latest vulnerability allows them to do it with a lot less effort. Frankly it's the last thing the web needs in this summer of me-too hacktivism.
