+
+A security flaw was found in the way ssh-keysign,
+a ssh helper program for host based authentication,
+attempted to retrieve enough entropy information on configurations that
+lacked a built-in entropy pool in OpenSSL (a ssh-rand-helper program would
+be executed to retrieve the entropy from the system environment).
+A local attacker could use this flaw to obtain unauthorized access to host keys
+via ptrace(2) process trace attached to the 'ssh-rand-helper' program.
