[Juan Uys <juan () fm ly>]

Good day Vuln-dev, (this is my first posting ;)

The exec-shield feature provides protection against stack, buffer or
function pointer overflows, and against other types of exploits that
rely on overwriting data structures and/or putting code into those
structures.

This seems promising, and I'm going to play around with it this weekend.
Has anyone checked this out yet? And, what are your views?

Have a good weekend,
