The H-Security: The PHP developers are working to fix a critical security vulnerability in PHP that they introduced with a recent security patch. The current stable release is affected; however, it is not yet clear whether the questionable patch was also applied to older versions. The cause of the problem is the security update to PHP 5.3.9, which was written to prevent denial of service (DoS) attacks using hash collisions. To do so, the developers limited the maximum possible number of input parameters to 1,000 in php_variables.c using max_input_vars.

The bug is considered to be critical as code can be remotely injected over the web. ...

SophosLabs: Facebook’s IPO is the most hyped initial public offering in years, with much speculation about just how many billions of dollars the social networking phenomenon will be valued at. There’s no doubt that 27-year-old Mark Zuckerberg, the founder of Facebook, is going to become a very rich man – and will be able to buy an even larger wardrobe of hoodies.
