Damn Vulnerable Linux

Damn Vulnerable Linux (DVL) is a live CD packed with broken, ill-configured, outdated, and exploitable software that makes it vulnerable to attacks. DVL isn’t built to run on your desktop – it’s a learning tool for security students. DVL is designed to be as vulnerable as possible, to teach topics such as reverse code engineering, buffer overflows, shellcode development, Web exploitation, and SQL injection. DVL was added to the list July 19, 2010.
