Backtrack Linux is full of really great tools including SQLScan which is a SQL Scanner that provides the ability to query Google for vulnerable hosts and extract MD5 hashes from the results. Unfortunately sqlscan.py was written for Python 2.3 or Python 2.4 and has not been maintained to be compatible with Python 2.6 which is the current version of Python installed on Backtrack Linux 5 R3. Backtrack 5 R3 is based off of Ubuntu 10.04 which had a release date of April, 2010 so needless to say some packages are out of date. It should be noted though that there is a lot to be said for stability in your operating system versus bleeding edge capabilities and I am sure when the time is correct the Backtrack team will be releasing a new version of Backtrack based on a newer version of Ubuntu.
After a recent upgrade from PHP 5.2 to PHP 5.2 on a CentOS Linux server I ran into some issues with a couple applications I had installed. One of the errors I noticed was generated by set_magic_quotes_runtime function which was deprecated in PHP 5.3. Fixing this error is easy by modifying any PHP files that include set_magic_quotes_runtime as shown in the below example.
