Ansible playbook symlink
|ansible-cve20134260-symlink (86898)||Medium Risk|
Ansible could allow a local attacker to launch a symlink attack. Temporary files are created insecurely within /var/tmp directory on failed run of playbook. A local attacker could exploit this vulnerability by creating a symbolic link from a temporary file to various files on the system, which could allow the attacker to overwrite arbitrary files on the system with elevated privileges.
Upgrade to the latest version of Ansible (1.2.3 or later), available from the Ansible Web site. See References.
