high Nessus Plugin ID 183136

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM / 22.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5315-1 advisory.

 It was discovered that Ansible did not properly manage directory permissions when running playbooks with an unprivileged become user. A local attacker could possibly use this issue to cause a race condition, escalate privileges and execute arbitrary code. This issue only affected Ubuntu 16.04 ESM, Ubuntu 18.04 ESM and Ubuntu 20.04 ESM. (CVE-2020-1733)

 It was discovered that the fix to address CVE-2020-1733 in Ansible was incomplete on systems using ACLs and FUSE filesystems. A local attacker could possibly use this issue to cause a race condition, escalate privileges and execute arbitrary code. This issue only affected Ubuntu 16.04 ESM, Ubuntu 18.04 ESM and Ubuntu 20.04 ESM. (CVE-2020-10744)

 It was discovered that Ansible did not properly manage multi-line YAML strings and special template characters. A local attacker could possibly use this issue to cause a template injection, resulting in the disclosure of sensitive information or other unspecified impact. (CVE-2021-3583)

 It was discovered that the ansible-connection module in Ansible did not properly manage certain error messages. A local attacker could possibly use this issue to expose sensitive information. This issue only affected Ubuntu 20.04 ESM and Ubuntu 22.04 ESM. (CVE-2021-3620)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected ansible, ansible-fireball and / or ansible-node-fireball packages.
