Scientific Linux Security Update : dhcp on SL5.x i386/x86_64 (20120803)

medium Nessus Plugin ID 61427

Language:

Synopsis

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

Description

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.

A denial of service flaw was found in the way the dhcpd daemon handled zero-length client identifiers. A remote attacker could use this flaw to send a specially crafted request to dhcpd, possibly causing it to enter an infinite loop and consume an excessive amount of CPU time.
(CVE-2012-3571)

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

Solution

Update the affected packages.
