Więcej informacji:

Ta porada bezpieczeństwa poprawia DSA 458-2, która powodowała błąd w wywołaniu gethostbyaddr.

Oryginalna porada brzmiała:

Sebastian Schmidt odkrył błąd przepełnienia bufora w funkcji getaddrinfo Pythona, który może pozwolić adresowi IPv6, podanego przez zdalnego atakującego poprzez DNS na nadpisanie pamięci na stosie.

Błąd ten istnieje w pythonie 2.2 i 2.2.1 i tylko wtedy gdy wyłączona jest obsługa IPv6. Pakiet python2.2 w Debianie woody uwzględnia te zastrzeżenia (pakiet 'python' ich nie uwzględnia).

W dystrybucji stabilnej (woody) powyższy błąd został naprawiony w wersji 2.2.1-4.6.

Dystrybucja testowa i niestabilna (sarge i sid) nie są narażone na ten błąd.

Zalecamy aktualizację pakietów python2.2.

Naprawiony w:

Debian GNU/Linux 3.0 (woody)
