The most conservative estimates indicate that, by the end of 2015, the share of IPv6 traffic will reach at least 10%, and this growth will continue. A special protocol for regional registries also came into force recently. Now, a new block of IPv4 addresses will be issued only if the company proves it has already implemented IPv6. So if anyone needs a subnetwork of white IPv4 addresses, they will need to implement IPv6. This fact will also encourage the further growth of IPv6 systems and lead to an increase in traffic. As far as ordinary users are concerned, providers began appearing all over the world, issuing real IPv6-addresses to end subscribers. And so, IPv6 will be encountered more and more often, and that’s a fact we cannot ignore.

Before turning to unconventional methods of usage, I will describe how “keep-alive” is working. The process is utterly simple – in a connection, multiple requests are sent instead of just one, and multiple responses come from the server. The benefits are obvious: there is less time spent on establishing connection, less load on CPU and memory. The number of requests in a single connection is usually limited by settings of the server (in most cases, there are at least several dozen). The procedure for establishing a connection is universal.

We will start with a definition. MySQL is a relational database management system with different data storage engines, such as MyISAM, InnoDB, Archive and others. Like most open source projects, it has its own branches, for example, MariaDB. Before going into details, I would like to mention that most of discussed vectors/techniques/bugs apply to various engines and branches, though not always.

Well, how could we ‘boost’ privileges on Windows? First of all, we should say that there were found, lately, a lot of vulnerabilities regarding fonts parsing which make the process of privileges elevation rather simple as long as we have a proper exploit. If you use the Metasploit then you need only one command to get the system shell. However, it will only work if the system is not fully patched. In case if the machine has all the updates installed, despite the Linux, we will not be able to find SUID-binaries in here, furthermore the environmental variables usually do not transmitted to services or processes with higher privileges. So, what we can do then?
