The fact of the version that run in OpenBSDs to allow bigger keys would be 
one bug? How this would place at risk my system?

It's a bug but it's been fixed (in OpenBSD 3.9 and up).  OpenSSH (both
OpenBSD's and -portable) used to allow DSA keys >1024 bits until several
people pointed out that a) it's not in line with the standard, and b) the
strength is limited by the use of SHA1 anyway.

Other than the fact that the larger DSA keys aren't as strong as larger
RSA keys and they have interoperability problems they do not represent
a risk to your system.

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
