Lisätietoa:

SuSEn tietoturvatarkistusryhmän Sebastian Krahmer havaitsi kaksi ongelmaa sambassa, suositussa SMB/CIFS-toteutuksessa. Ongelmat ovat:

puskurin ylivuoto smbd:n käyttämässä SMB/CIFS-pakettisirpaleiden uudelleenkoontikoodissa. Koska smbd:tä ajetaan root-oikeuksilla, hyökkääjä voi hyödyntää tätä saadakseen root-oikeudet koneelle jolla smbd:tä ajetaan.
reg-tiedostojen kirjoittamiseen käytettävä koodi oli altis chown-kilpailutilanteelle, minkä johdosta paikallisen käyttäjän oli mahdollista ylikirjoittaa järjestelmätiedostoja

Molemmat ongelmat on korjattu tulevassa 2.2.8-versiossa, ja Debian GNU/Linux 3.0/woody-paketin versiossa 2.2.3a-12.1 .

Korjattu:

Debian GNU/Linux 3.0 (woody)
