Debian OpenSSH/OpenSSL Package Random Number Generator Weakness
Critical Nessus Plugin ID 32314
Synopsis
The remote SSH host keys are weak.
Description
The remote SSH host key has been generated on a Debian or Ubuntu system which contains a bug in the random number generator of its OpenSSL library.
The problem is due to a Debian packager removing nearly all sources of entropy in the remote version of OpenSSL.
An attacker can easily obtain the private part of the remote key and use this to set up decipher the remote session or set up a man in the middle attack.
Solution
Consider all cryptographic material generated on the remote host to be guessable. In particuliar, all SSH, SSL and OpenVPN key material should be re-generated.
