Bug #9790: TOCTOU vulnerability in ssh_authorized_keys.

Target version: 
Affected Puppet version: 
Keywords: 
Branch: 


There was a TOCTOU vulnerability in ssh_authorized_keys, and theoretically in 
the Solaris and AIX providers, where file ownership was given away before it 
was written.  This was bad, because it allowed a user to overwrite arbitrary 
files as root, if their authorized_keys file was managed.
