Hi wonderful peeps of this forum. I just got the following email from Bluehost, about my site that I’m running on Network

The timthumb.php file is a script commonly used in WordPress’s (and other software’s) themes and plugins to resize images. The exploit allows an attacker to arbitrarily upload and create files and/or folders on your account, which can then be used for a number of malicious tasks, including but not limited to defacement, browser high-jacking and infection, data harvesting and more. After a site has been exploited, it may lead to becoming labeled a “Malicious Website” by Google or other security authorities.

Any timthumb.php file below version 1.35, but above version 1.09 is considered vulnerable, unless patched. To prevent being compromised, we advise you update all instances of timthumb.php to version 2.0, or patch the existing vulnerable files. Note that patching the files requires more in-depth knowledge of the PHP scripting language.

The updated version of timthumb.php can be found here:
