Description:
Tavis Ormandy has reported a vulnerability in OpenSSH, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error within the handling of multiple identical blocks in a ssh packet. If ssh protocol 1 is enabled, this can be exploited to cause a DoS due to CPU consumption by sending specially crafted ssh packets.
