    Hi there, my Friends. :D

    here, i'd like to discuss the possible & the best techniques for subj. 1st & foremost, i would like to share my humble approach to protect buffers.

    code: http://sourceforge.net/projects/dasofi/
    description: http://alg0z.blogspot.ru/2014/10/dabofi.html

    perhaps, description seems too short, but i hope code is more verbose ;)

    Thanks, but what makes your project special? What programming language is it in? How is it different than other solutions?

    Seems a little odd to come back after 5 years just to post this with very little explanation as to why it is supposedly helpful :)

    Markus, it's for C/C++. standard approaches to fight versus OF:

    1. ASLR.
    2 NX bit.
    3. Canaries.

    my humble method has minimal performance penalty & can be easily adapted (in comparison w/ other approaches) to different strategies of memory management ;)
