qmail starttls patch does not seed the random number generator

openssl-0.9.6b does not allow ssl/tls connections when the random number has not been seeded. This is a good idea, and it exposes that the starttls patch for qmail does not seed the random number generator. Here is a small patch that fixes the problem in qmail-remote for systems that support...

SSH-1 allows client authentication to be forwarded by a malicious server to another server

Overview A design flaw in the SSH-1 protocol allows a malicious server to establish two concurrent sessions with the same session ID, allowing a man-in-the-middle attack. The client must accept unknown host keys from the malicious server to enable exploitation of this vulnerability. Description...
