Scientific Linux Security Update : dhcp on SL4.x, SL5.x, SL6.x i386/x86_64

High Nessus Plugin ID 61110


The remote Scientific Linux host is missing one or more security updates.


The Dynamic Host Configuration Protocol (DHCP) is a protocol that allows individual devices on an IP network to get their own network configuration information, including an IP address, a subnet mask, and a broadcast address.

Two denial of service flaws were found in the way the dhcpd daemon handled certain incomplete request packets. A remote attacker could use these flaws to crash dhcpd via a specially crafted request.
(CVE-2011-2748, CVE-2011-2749)

Users of DHCP should upgrade to these updated packages, which contain a backported patch to correct these issues. After installing this update, all DHCP servers will be restarted automatically.


Update the affected packages.
