U radu programskog paketa Samba uočeno je više sigurnosnih propusta. Udaljeni ih napadač može iskoristiti za DoS (eng. Denial of Service) napad te izvršavanje proizvoljnog programskog koda.
Paket:
Samba 3.x
Operacijski sustavi:
SUSE Linux Enterprise Desktop 11, SUSE Linux Enterprise Server (SLES) 11
Kritičnost:
8.7
Problem:
neodgovarajuće rukovanje memorijom, pogreška u programskoj funkciji, pogreška u programskoj komponenti, preljev međuspremnika
Sigurnosne ranjivosti su posljedica preljeva međuspremnika u funkciji "process.c", curenja memorije u komponenti "smbd" te pogrešne provjere veličine polja u komponenti "RPC code generator".
Posljedica:
Udaljeni napadač navedene ranjivosti može iskoristiti za proizvoljno pokretanje programskog koda te napad uskraćivanja usluga (DoS).
Rješenje:
Svim se korisnicima navedenog programskog paketa, u svrhu zaštite sigurnosti, savjetuje njegova nadogradnja na novije inačice.

returned by the NetrSamLogonEx call is timeout in the
pam_auth_crap path; (bso#8771).
* s3-winbindd: set the can_do_validation6 also for
trusted domain; (bso#8599).
* Fix problem when calculating the share security mask,
take priviliges into account for the connecting user;
(bso#8784).
