HIGH 7.3WATCHLISTUPGRADEMITIGATE

CVE-2019-14904 is a high-severity flaw (CVSS 7.3) affecting ansible, debian linux. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A flaw was found in the solaris_zone module from the Ansible Community modules. When setting the name for the zone on the Solaris host, the zone name is checked by listing the process with the 'ps' bare command on the remote machine. An attacker could take advantage of this flaw by crafting the name of the zone and executing arbitrary commands in the remote host. Ansible Engine 2.7.15, 2.8.7, and 2.9.2 as well as previous versions are affected.

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
