high Nessus Plugin ID 128881

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Several vulnerabilities were discovered in Ansible, a configuration management, deployment, and task execution system.

CVE-2015-3908

A potential man-in-the-middle attack associated with insusfficient X.509 certificate verification. Ansible did not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

CVE-2015-6240

A symlink attack that allows local users to escape a restricted environment (chroot or jail) via a symlink attack.

CVE-2018-10875

A fix potential arbitrary code execution resulting from reading ansible.cfg from a world-writable current working directory. This condition now causes ansible to emit a warning and ignore the ansible.cfg in the world-writable current working directory.

CVE-2019-10156

Information disclosure through unexpected variable substitution.

For Debian 8 'Jessie', these problems have been fixed in version 1.7.2+dfsg-2+deb8u2.

We recommend that you upgrade your ansible packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
