		<description><![CDATA[Heap-spraying is an interesting type of attack which allocates thousands of malicious objects to the heap in order to exploit a vulnerability of the application (Adobe Reader, Safari, Mozilla Firefox, Internet Explorer). In the presence of a memory corruption or buffer overflow vulnerability, a heap-spraying attack has been shown to be very effective (also with [...]]]></description>

		<description><![CDATA[When NetBSD and FreeBSD swap out a page from a process, they look in the process virtual address space to find nearby pages that are also candidates for being swapped out. This greatly increases the chance of swapin IO pulling in related data, reducing the number of disk seeks involved in swap IO (from kernelnewbies.org). [...]]]></description>

		<description><![CDATA[In the last ten years the web has evolved from a set of interconnected static pages to a system of complex, distributed applications and active content. Traditional browsers are no more appropriate tools to handle such contents and many security issues have arisen from the usage of tools designed to handle traditional types of content.<br />
Insufficient studies have been accomplished to surf the new contents of the Internet, referring to dynamic and potentially malicious applications.]]></description>

Since these attacks require knowledge of the memory layout schema, the basic idea to design a countermeasure is to randomize locations of target memory [...]]]></description>
