Summary

Piranha provides high-availability and load-balancing services for Red Hat Enterprise Linux. The piranha packages contain various tools to administer and configure the Linux Virtual Server (LVS), as well as the heartbeat and failover components. LVS is a dynamically-adjusted kernel routing mechanism that provides load balancing, primarily for Web and FTP servers.
It was discovered that the Piranha Configuration Tool did not properly restrict access to its web pages. A remote attacker able to connect to the Piranha Configuration Tool web server port could use this flaw to read or modify the LVS configuration without providing valid administrative credentials. (CVE-2013-6492)
This update also fixes the following bug:
* When the lvsd service attempted to start, the sem_timedwait() function received the interrupted function call (EINTR) error and exited, causing the lvsd service to fail to start. With this update, EINTR errors are correctly ignored during the start-up of the lvsd service. (BZ#1055709)
All piranha users are advised to upgrade to this updated package, which contains backported patches to correct these issues.
