Upgrade ansible
to version 2.7.17, 2.8.9, 2.9.6 or higher.
Overview
ansible is a simple IT automation system.
Affected versions of this package are vulnerable to Race Condition. A race condition flaw exists when running a playbook with an unprivileged become user. When Ansible needs to run a module with become user, the temporary directory is created in /var/tmp
. This directory is created with umask 77 && mkdir -p <dir>;
. This operation does not fail if the directory already exists and is owned by another user. An attacker could take advantage to gain control of the become user as the target directory can be retrieved by iterating /proc/<pid>/cmdline
.
