CVE-2018-10875

ansible.cfg was read from the current working directory.

CVE-2018-16837

The user module leaked parameters passed to ssh-keygen to the process environment.

CVE-2019-3828

The fetch module was susceptible to path traversal.

For the stable distribution (stretch), these problems have been fixed in version 2.2.1.0-2+deb9u1.

We recommend that you upgrade your ansible packages.

For the detailed security status of ansible please refer to its security tracker page at: [link moved to references]");
