Facter is a cross-platform Ruby library for retrieving facts from operating systems.
Facter includes the current working directory in the search path.
A local attacker may be able to gain escalated privileges.
There is no known workaround at this time.
All Facter users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-ruby/facter-1.7.6"
