CVE-2020-25654

Pacemaker is an advanced, scalable High-Availability cluster resource manager.

Security Fix(es):

An ACL bypass flaw was found in pacemaker. An attacker having a local account on the cluster and in the haclient group could use IPC communication with various daemons directly to perform certain tasks that they would be prevented by ACLs from doing if they went through the configuration.(CVE-2020-25654)

ACL restrictions bypass. (CVE-2020-25654)

This update for pacemaker fixes the following issues:

Update to 2.0.4:

• based: use crm_exit to free qb-logging
• cibsecret: don't use pssh -q option unless supported
• crm_error: use g_free for a proper match
• crm_mon: NULL output-pointer when buffer is freed
• crm_resource: avoid unnecessary issus with dynamic allocation
• crm_ticket: avoid unnecessary issues with dynamic allocation
• executor: restrict certain IPC requests to Pacemaker daemons (CVE-2020-25654, bsc#1177916)
• fencer: avoid infinite loop if device is removed during operation
• fencer: restrict certain IPC requests to privileged users (CVE-2020-25654, bsc#1177916)
• libcrmcommon: free basename after setting prgname
• libcrmcommon: return ENOMEM directly instead of errno
• libpe_status: Modify filtering of inactive resources.
• libreplace: closedir when bailing out dir traversal
• move bcond_with/without up front for e.g. pcmk_release
• pacemakerd: ignore shutdown requests from unprivileged users (CVE-2020-25654, bsc#1177916)
• resources: attribute name parameter doesn't have to be unique
• rpm: add spec option for enabling CIB secrets
• rpm: put user-configurable items at top of spec
• rpm: use the user/group ID 90 for haclient/hacluster to be consistent with cluster-glue (bsc#1167171)
• scheduler: Add the node name back to bundle instances.
• silence some false positives static analysis stumbled over
• tools: check resource separately from managing parameter in cibsecret
• tools: free IPC memory after closing connection
• tools: improve cibsecret help
• tools: verify newly created CIB connection is not NULL

Ken Gaillot discovered that Pacemaker incorrectly handled IPC communications permissions. A local attacker could possibly use this issue to bypass ACL restrictions and execute arbitrary code as root.
