"The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the
dsa-4950 advisory.
Several vulnerabilities have been found in Ansible, a configuration management, deployment and task
execution system, which could result in information disclosure or argument injection. In addition a race
condition in become_user was fixed. For the stable distribution (buster), these problems have been fixed
in version 2.7.7+dfsg-1+deb10u1. We recommend that you upgrade your ansible packages. For the detailed
security status of ansible please refer to its security tracker page at: https://security-
tracker.debian.org/tracker/ansible
Tenable has extracted the preceding description block directly from the Debian security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
