Referenser i säkerhetsdatabaser:

I Mitres CVE-förteckning: CVE-2003-0026.
CERTs information om sårbarheter, bulletiner och incidenter: VU#284857, CA-2003-01.

Ytterligare information:

Internet Software Consortium upptäckte flera sårbarheter under en genomgång av ISCs DHCP-server. Sårbarheterna förekommer i felhanteringsrutiner inuti miniresbiblioteket och kan utnyttjas som stackspill. Detta kan möjliggöra för en angripare utifrån att exekvera godtycklig kod med det användar-id dhcpd kör under, vanligtvis root. Andra DHCP-servrar än dhcp3 verkar inte påverkas.

För den stabila utgåvan (Woody) har detta problem rättats i version 3.0+3.0.1rc9-2.1.

Den gamla stabila utgåvan (Potato) innehåller inte några dhcp3-paket.

För den instabila utgåvan (Sid) har detta problem rättats i version 3.0+3.0.1rc11-1.

Vi rekommenderar att ni uppgraderar ert dhcp3-server-paket.
