3 | A security flaw was found in the way ssh-keysign, | ||

5 | attempted to retrieve enough entropy information on configurations that | ||
6 | lacked a built-in entropy pool in OpenSSL (a ssh-rand-helper program would | ||

8 | A local attacker could use this flaw to obtain unauthorized access to host keys | ||
