RHBA-2015:1212 - Bug Fix Advisory

Topic

Updated dhcpv6 packages that fix one bug are now available for Red Hat
Enterprise Linux 5.

Description

The dhcpv6 packages implement the Dynamic Host Configuration Protocol (DHCP) for
Internet Protocol version 6 (IPv6) networks, in accordance with RFC 3315:
Dynamic Host Configuration Protocol for IPv6 (DHCPv6). DHCP is a protocol that
allows individual devices on an IP network to get their own network
configuration information. It consists of: dhcp6c(8), the DHCPv6 client daemon;
dhcp6s(8), the DHCPv6 server daemon; and dhcp6r(8), the DHCPv6 relay agent.

This update fixes the following bug:

• Previously, the dhcpv6 client terminated unexpectedly with a segmentation

fault when it was running in client mode and an invalid lease was stored on the
disk. With this update, the lease hash table is initialized correctly in client
mode, which allows the dhcpv6 client to handle invalid leases as expected.
(BZ#1229441)

Users of dhcpv6 are advised to upgrade to these updated packages, which fix this
bug.
