The create_script
function in the lxc_container
module in Ansible before 1.9.6-1 and 2.x before 2.0.2.0 allows local users to write to arbitrary files or gain privileges via a symlink attack on (1) /opt/.lxc-attach-script
, (2) the archived container in the archive_path
directory, or the (3) lxc-attach-script.log
or (4) lxc-attach-script.err
files in the temporary directory.
