Gentoo update for Ansible

1) Code Injection

EUVDB-ID: #VU29017

Risk: Low

CVSSv4.0: 4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2020-10684

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

Exploit availability: No

Description

The vulnerability allows a local user to execute arbitrary code on the target system.

The vulnerability exists due to improper input validation when using "ansible_facts" as a subkey of itself and promoting it to a variable when inject is enabled, overwriting the "ansible_facts" after the clean. A local user can alter the "ansible_facts", such as "ansible_hosts", "users" and any other key data which would lead into privilege escalation or code injection

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
