::: New w0rm (Linux.Darlloz) Creates Havoc for Linux PC's :::

What is Computer W0rm ?

A computer worm is a standalone malware computer program that replicates itself in order to spread to other computers.Often, it uses a computer network to spread itself, relying on security failures on the target computer to access it. Unlike a computer virus, it does not need to attach itself to an existing program. Worms almost always cause at least some harm to the network, even if only by consuming bandwidth, whereas viruses almost always corrupt or modify files on a targeted computer.

Linux.Darlloz - A new worm is targeting x86 computers running Linux and PHP, and variants may also pose a threat to devices such as home routers and set-top boxes based on other chip architectures.

According to security researchers from Symantec, the malware spreads by exploiting a vulnerability in php-cgi, a component that allows PHP to run in the Common Gateway Interface (CGI) configuration. The vulnerability is tracked as CVE-2012-1823 and was patched in PHP 5.4.3 and PHP 5.3.13 in May 2012.

The new worm, which was named Linux.Darlloz, is based on proof-of-concept code released in late October, the Symantec researchers said Wednesday in a blog post.
