Old OpenSSH and OpenSSL versions. Other libs are almost ancient if you are used to Arch/Gentoo/Slackware. All the classical Debian based problems.
The collection of available tools is pretty nice, but not always up to date.
I favor the Light version, because it uses XFCE. As such, it comes with about 5 pentesting apps, and virtually nothing else. I LOVE the grub background image, and the user default as root (like Puppy). It DID force me to learn to use apt-get install from the command line, which was a good thing.
