    Package : pacemaker
    CVE ID : CVE-2020-25654
    Debian Bug : 973254

    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: https://security-tracker.debian.org/tracker/pacemaker
