CVE-2011-4327: Infoleak
First published: Mon Nov 21 2011(Updated: )
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.
