RHBA-2014:0757 - Bug Fix Advisory

Topic

Updated dnsmasq packages that fix one bug are now available for Red Hat
Enterprise Linux 6.

Description

The dnsmasq packages contain Dnsmasq, a lightweight domain name system (DNS)
forwarder and dynamic host configuration protocol (DHCP) server.

This update fixes the following bug:

• Previously, the Dnsmasq service status verification in the init script was not

sufficiently robust and only determined the presence of all the instances of
Dnsmasq running on the system. As a consequence, the init script identified
Dnsmasq as running even when no Dnsmasq system instance had been initiated. The
init script has been fixed to explicitly verify the process with the process ID
written in the PID file of the system instance. As a result, the status of the
Dnsmasq system instance is now identified correctly even if there are running
instances not started by the init script. (BZ#991473)

Users of dnsmasq are advised to upgrade to these updated packages, which fix
this bug.

Solution

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