>From their blog post:

"C++ lends itself to much more

plain old C. From templates to string classes, C++ raises the skill
level required to play the memory corruption game. And while the quality of
C/C++ code we see has increased dramatically over the years, a lot of
developers still don’t understand the more obscure C++ bug classes. I
recently found a vulnerable C++ code pattern that I wanted to share with our
readers. But instead of just writing some boring technical blog post,
Matasano would like to present a C++ audit challenge to our audience. It
consists of a contrived vulnerability that follows the same vulnerable code
pattern. "
