"The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2011-306:02 advisory.

    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.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
