I Mitres CVE-förteckning: CVE-2009-0692, CVE-2009-1892.
CERTs information om sårbarheter, bulletiner och incidenter: VU#410676.

Ytterligare information:

Flera utifrån nåbara sårbarheter har upptäckts i ISC:s DHCP-implementation:

CVE-2009-0692
Det upptäcktes att dhclient inte hanterar för långa subnetmaskalternativ på ett bra sätt, vilket leder till ett stackbaserat buffertspill och möjlig exekvering av godtycklig kod.
CVE-2009-1892
Christoph Biedl upptäckte att DHCP-servern kan avslutas när den erhåller särskilda välformade DHCP-förfrågningar, under förutsättning att serverkonfigurationen blandar värddefinitioner som använder "dhcp-client-identifier" och "hardware ethernet". Denna sårbarhet påverkar bara Lenny-versionerna av dhcp3-server och dhcp3-server-ldap.

För den gamla stabila utgåvan (Etch) har dessa problem rättats i version 3.0.4-13+etch2.

För den stabila utgåvan (Lenny) har dessa problem rättats i version 3.1.1-6+lenny2.

För den instabila utgåvan (Sid) kommer dessa problem att rättas inom kort.

Vi rekommenderar att ni uppgraderar era dhcp3-paket.
