2. Relevant releases/architectures:
OpenStack Folsom - noarch
PackStack is a command line utility that uses Puppet modules to support
rapid deployment of OpenStack on existing servers over an SSH connection.
PackStack is suitable for deploying both single node proof of concept
installations and more complex multi-node installations.
It was found that PackStack did not handle the answer file securely. In
some environments, such as those using a non-default umask, a local
attacker could possibly modify the answer file if PackStack was run in an
attacker controlled directory, or attempted to create the answer file in
"/tmp/", allowing the attacker to modify systems being deployed using
OpenStack. Note: After applying this update, PackStack will create the
answer file in the user's home directory by default. It will no longer
create it in the current working directory or the "/tmp/" directory by
The CVE-2013-1815 issue was discovered by Derek Higgins of the Red Hat
