Description

It was discovered that there was an in issue in the command-line tool for the Pacemaker High Availability stack. Local attackers were able to execute commands via shell code injection to the 'crm history' command-line tool, potentially allowing escalation of privileges.

For Debian 9 'Stretch', this problem has been fixed in version 2.3.2-4+deb9u1.

We recommend that you upgrade your crmsh packages.
