Beskrivelse:
Der er rapporteret en sårbarhed i rsync, som potentielt kan udnyttes af ondsindede brugere til at læse eller skrive vilkårlige filer på et sårbart system.

Sårbarheden skyldes en inputvalideringsfejl i funktionen "sanitize_path()".

Succesfuld udnyttelse forudsætter, at rsync-daemonen ikke kører chrooted.

Sårbarheden berører version 2.6.2 og tidligere.

Løsning:
En rettelse er tilgængelig via CVS og bliver også inkluderet i version 2.6.3.

Producenten anbefaler, at konfigurere "use chroot = true" for alle moduler i konfigurationsfilen "rsyncd.conf".
