DSA-231-1 dhcp3 -- pinon ylivuotoja

Ilmoitettu:

17. 1.2003

Vaikutuksen alaiset paketit:

dhcp3

Altis:

Kyllä

Viittaukset tietoturvatietokantoihin:

Mitren CVE-sanakirjassa: CVE-2003-0026.
CERT:n alttiudet, tiedotteet ja ongelmahuomiot: VU#284857, CA-2003-01.

Lisätietoa:

The Internet Software Consortium havaitsi useita haavoittuvuuksia ISC DHCP-taustasovelluksessa sitä tarkistaessaan. Haavoittuvuudet sijaitsevat minires-kirjaston virheenkäsittelyrutiineissa ja ovat mahdollisesti hyväksikäytettävissä pinoylivuotojen muodossa. Sitä kautta etähyökkääjän voi olla mahdollista ajaa mielivaltaista koodia dhcpd:n käyttäjätunnuksella, yleensä root-oikeuksilla. Muut DHCP-palvelimet kuin dhcp3 eivät näytä olevan alttiita.

Ongelma on korjattu vakaan jakelun (woody) versiossa 3.0+3.0.1rc9-2.1 .

Aiempi vakaa jakelu (potato) ei sisällä dhcp3-paketteja.

Ongelma on korjattu epävakaan jakelun (sid) versiossa 3.0+3.0.1rc11-1 .

Suosittelemme päivittämään dhcp3-server-paketin.

Korjattu:

Debian GNU/Linux 3.0 (woody)
