Test ID:1.3.6.1.4.1.25623.1.0.704791
Category:Debian Local Security Checks
Title:Debian: Security Advisory for pacemaker (DSA-4791-1)
Summary:The remote host is missing an update for the 'pacemaker'; package(s) announced via the DSA-4791-1 advisory.
Description:Summary:
The remote host is missing an update for the 'pacemaker'
package(s) announced via the DSA-4791-1 advisory.

Vulnerability Insight:
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.

Affected Software/OS:
'pacemaker' package(s) on Debian Linux.

Solution:
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.

CVSS Score:
5.0
