GNU is a big organization, with different people, and maybe some common
policies. About security policies you might want to contact the gnu
maintainers mailing list, or some other internal list. My relation with
FSF and GNU is only the fact that GNUTLS is part of GNU, and I
transferred copyright to FSF. I'm not actively involved organizationally.

I thought you were familiar with the gnutls internals. In any case,
GnuTLS uses its own string functions, internally, which have no issues
related to buffer overflows. The only cases where we use the libc
functions, such as snprintf and friends, is when the strings are static,
and will not exceed the given buffers. If you have some example where
this is not case please report it (I already explained that in a
If you are referring to overflow of the test program gnutls-serv, I
wouldn't care that much. It is a testing program, not one expected to be
run in a non-developer's PC.

Please don't confuse me, with GNU.
