Title:	Conectiva Security Advisory CLA-2003:616
Summary:	NOSUMMARY
Description:	Description: The remote host is missing updates announced in advisory CLA-2003:616. The package dhcp provides a Dynamic Host Configuration Protocol[1] server developed by ISC (ISC DHCPD). Florian Lohoff discovered[2] a vulnerability[3,4] in the way dhcrelay (part of the dhcp package) forwards malicious BOOTP packets it receives to the dhcp servers it contacts. An attacker could exploit this vulnerability to generate a storm of BOOTP packets, causing a denial of service condition or a misbehavior by the part of the dhcp server. The Common Vulnerabilities and Exposures project (cve.mitre.org) is tracking[5] this issue with the name CVE-2003-0039. The packages provided with this announcement fix these vulnerabilities with a patch, keeping the original version. Please note that Conectiva Linux versions prior to 8 do not ship dhcp 3.0 and therefore are not vulnerable to this problem. Solution: The apt tool can be used to perform RPM package upgrades by running 'apt-get update' followed by 'apt-get upgrade' http://www.ietf.org/rfc/rfc2131.txt http://online.securityfocus.com/archive/1/307451 http://online.securityfocus.com/bid/6628 http://www.kb.cert.org/vuls/id/149953 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2003-0039 http://www.securityspace.com/smysecure/catid.html?in=CLA-2003:616 http://distro.conectiva.com.br/atualizacoes/index.php?id=a&anuncio=002003 Risk factor : Medium CVSS Score: 5.0
