Debian DSA-1833-1 : dhcp3 - several vulnerabilities

Description

Several remote vulnerabilities have been discovered in ISC's DHCP implementation : - CVE-2009-0692 It was discovered that dhclient does not properly handle overlong subnet mask options, leading to a stack-based buffer overflow and possible arbitrary code execution. - CVE-2009-1892 Christoph Biedl discovered that the DHCP server may terminate when receiving certain well-formed DHCP requests, provided that the server configuration mixes host definitions using 'dhcp-client-identifier' and 'hardware ethernet'. This vulnerability only affects the lenny versions of dhcp3-server and dhcp3-server-ldap.
