Debian/Ubuntu - OpenSSH 보안 위험

weakness has been discovered in the random number generator used by OpenSSL on Debian and Ubuntu systems. As a result of this weakness, certain encryption keys are much more common than they should be, such that an attacker could guess the key through a brute-force attack given minimal knowledge of the system. This particularly affects the use of encryption keys in OpenSSH.

1. Install the security updates
2. Update OpenSSH known_hosts files
3. Check all OpenSSH user keys
4. Regenerate any affected user keys
5. Update authorized_keys files (if necessary)
