fwb_install in fwbuilder 2.1.19 allows local users to overwrite arbitrary
files via a symlink attack on a /tmp/ssh-agent.##### temporary file. 

Note: the description only indicates 2.1.19 but I have verified this issue
affects both Fedora 9 and 10.  There are no ssh-agent calls in fwbuilder as
packaged in Fedora 11.
