* SECURITY UPDATE: Remote DoS.
* CVE-2006-4924: Fix a pre-authentication denial of service found by
  Tavis Ormandy, that would cause sshd(8) to spin until the login grace
  time expired.
  Upstream fixes:
  http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/deattack.c.diff?r1=1.29&r2=1.30&sortby=date&f=h

  http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/deattack.h.diff?r1=1.9&r2=1.10&sortby=date&f=h
* Fix an unsafe signal hander reported by Mark Dowd. The
  signal handler was vulnerable to a race condition that could be
  exploited to perform a pre-authentication denial of service. [CVE-2006-5051]
  On portable OpenSSH, this vulnerability could theoretically lead to
  pre-authentication remote code execution if GSSAPI authentication is
  enabled, but the likelihood of successful exploitation appears remote.
  [CVE-2006-5052]
* Above patches taken from Debian's 4.3p2-4 version, thanks to Colin Watson
  for backporting them from 4.4p1.
