Description Agostino Sarubbo gentoo-dev 2016-04-02 10:49:35 UTC
From ${URL} :

A vulnerability in lxc_container, ansible module, was found allowing to get root inside the container. The 
problem is in the create_script function, which tries to write to /opt/.lxc-attach-script inside of the 
container. If the attacker can write to /opt/.lxc-attach-script before that, he can overwrite arbitrary 
files or execute commands as root.


@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.

CVE-2016-3096 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2016-3096):
  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.
