Título:	Conectiva Security Advisory CLA-2002:483
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory CLA-2002:483. dhcp is a Dynamic Host Configuration Protocol Server and Client. Versions ranging from 3 to 3.0.1rc8 (inclusive) have a format string vulnerability[1] that could be exploited remotely. Considering the usage of the DHCP service, this usually means the local area network in this case. By default, these versions of DHCP are compiled with the dns update feature enabled. This feature allows the DHCP service to update dns records. The code in DHCP that logs this update has a format string vulnerability that could be exploited, since the update message contains data provided by the attacker, such as a hostname. A successful exploitation would give an attacker the same privileges the DHCP daemon has, tipically root. This vulnerability was discovered and researched by Fermín J. Serna from Next Generation Security Technologies[2] and published in coordination with CERT. Solution: The apt tool can be used to perform RPM package upgrades by running 'apt-get update' followed by 'apt-get upgrade' https://secure1.securityspace.com/smysecure/catid.html?in=CLA-2002:483 http://distro.conectiva.com.br/atualizacoes/index.php?id=a&anuncio=002002 Risk factor : High
