* 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.

* 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.

openssh (1:3.9p1-1ubuntu2.2) hoary-security; urgency=low
* SECURITY UPDATE: Shell code injection with crafted file names in scp.
* Ported upstream patch from 4.3p2 to replace system() call with a proper
exec() call; this avoids expanding shell metacharacters in local-to-local
or remote-to-remote copies.
* CVE-2006-0225
