Mandriva Linux Security Advisory MDKSA-2006-179: Tavis Ormandy of the Google Security Team discovered a Denial of Service vulnerability in the SSH protocol version 1 CRC compensation attack detector. This could allow a remote unauthenticated attacker to trigger excessive CPU utilization by sending a specially crafted SSH message, which would then deny ssh services to other users or processes (CVE-2006-4924, CVE-2006-4925). Please note that Mandriva ships with only SSH protocol version 2 enabled by default.
