dhcp-4.1.1-19.P1.AXS4.1

DHCP (Dynamic Host Configuration Protocol) is a protocol which allows
individual devices on an IP network to get their own network
configuration information (IP address, subnetmask, broadcast address,
etc.) from a DHCP server. The overall purpose of DHCP is to make it
easier to administer a large network. The dhcp package includes the
ISC DHCP service and relay agent.
To use DHCP on your network, install a DHCP service (or relay agent),
and on clients run a DHCP client daemon. The dhcp package provides
the ISC DHCP service and relay agent.
Security issues fixed with this release:
CVE-2011-2748
The server in ISC DHCP 3.x and 4.x before 4.2.2, 3.1-ESV before 3.1-ESV-R3, and 4.1-ESV before 4.1-ESV-R3 allows remote attackers to cause a denial of service (daemon exit) via a crafted DHCP packet.
CVE-2011-2749
The server in ISC DHCP 3.x and 4.x before 4.2.2, 3.1-ESV before 3.1-ESV-R3, and 4.1-ESV before 4.1-ESV-R3 allows remote attackers to cause a denial of service (daemon exit) via a crafted BOOTP packet.
Fixed bugs:
- Added the DHCRELAYARGS variable to the /etc/sysconfig/dhcrelay configuration file to pass additional arguments to the dhcrelay daemon
- The dhclient utility now logs its PID properly in syslog entries.
- Fixed the dhclient date strings parsing in lease files.
- Now, while updating the search entry, the dhclient utility always adds the domain part of the host name given to the client if it is missing.
- The dhcpd service with IPv6 could someitmes create a lease file that it was unable to parse. The service would then go into a loop and not start after being restarted. This has been fixed.
- Some ISPs DHCP servers send their clients 576 for the interface-mtu option value. Such a low MTU can cause throughput problems with UDP traffic. The dhclient utility now sets the interface MTU only if the value obtained from the server is higher than 576.
- added the LICENSE file to the dhclient package.
Enhancements:
- Implemented the Classless Static Route Options for DHCPv4 (RFC 3442), which supplies network route configuration to a large number of hosts without individual configuration of each one.
- Added support for IPoIB (IP over InfiniBand) interfaces.
