  script_tag(name:"insight", value:"Ken Gaillot discovered a vulnerability in the Pacemaker cluster resource manager: If ACLs were configured for users in the haclient group, the ACL restrictions could be bypassed via unrestricted IPC communication, resulting in cluster-wide arbitrary code execution with root privileges.

If the enable-acl cluster option isn't enabled, members of the haclient group can modify Pacemaker's Cluster Information Base without restriction, which already gives them these capabilities, so there is no additional exposure in such a setup.

For the stable distribution (buster), this problem has been fixed in version 2.0.1-5+deb10u1.

We recommend that you upgrade your pacemaker packages.

For the detailed security status of pacemaker please refer to its security tracker page at: [link moved to references]");
