Details
Tavis Ormandy discovered that the SSH daemon did not properly handle
authentication packets with duplicated blocks. By sending specially
crafted packets, a remote attacker could exploit this to cause the ssh
daemon to drain all available CPU resources until the login grace time
expired. (CVE-2006-4924)
Mark Dowd discovered a race condition in the server’s signal handling.
A remote attacker could exploit this to crash the server.
(CVE-2006-5051)
