漏洞信息
The Pacemaker cluster resource manager is a collection of technologies working together to provide data integrity and the ability to maintain application availability in the event of a failure.
Security Fix(es):
* An authorization flaw was found in Pacemaker, where it did not properly guard its IPC interface. An attacker with an unprivileged account on a Pacemaker node could use this flaw to, for example, force the Local Resource Manager daemon to execute a script as root and thereby gain root access on the machine. (CVE-2016-7035)
This issue was discovered by Jan "poki" Pokorny (Red Hat) and Alain Moulle (ATOS/BULL).
Bug Fix(es):
* The version of Pacemaker in Red Hat Enterprise Linux 7.3 incorporated an increase in the version number of the remote node protocol. Consequently, cluster nodes running Pacemaker in Red Hat Enterprise Linux 7.3 and remote nodes running earlier versions of Red Hat Enterprise Linux were not able to communicate with each other unless special precautions were taken. This update preserves the rolling upgrade capability. (BZ#1389023)
