  Fixes multiple remotely-triggered DoSes


For the lenny-backports distribution the problems have been fixed in
version 2.7.3-1~bpo50+2.

For the unstable (sid) distribution, the problem has been fixed in version 
2.7.4-1, for testing (squeeze) the fix should hopefully follow soon.

We recommend to pin the backports repository to 200 so that new
versions of installed  backports will be installed automatically.
