Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

An updated piranha package that fixes one security issue and one bug
is now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
Important security impact. A Common Vulnerability Scoring System
(CVSS) base score, which gives a detailed severity rating, is
available from the CVE link in the References section.

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.
