openssh (1:4.2p1-7ubuntu3.1) dapper-security; urgency=low

  * 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:

  * 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.
  * packet.c: Fix a NULL dereference crash so that an appropriate error
    message is printed on a protocol error. This is not actually a
    vulnerability, but has been assigned CVE-2006-4925, so let's fix it for
    completeness' sake.
