for an address that had been previously declined and internally tagged
as abandoned. Processing such a message could trigger an assert
failure that could crash dhcpd if it was running as a DHCPv6 server.
DHCPv4 servers are unaffected. (CVE-2011-0413)

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
