1. Summary:

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Load Balancer (v. 6) - i386, x86_64

3. Description:

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.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
