CVE-2008-5398
HighSummary
Tor w wersjach przed 0.2.0.32 nieprawidłowo przetwarza opcję konfiguracyjną ClientDNSRejectInternalAddresses w sytuacjach, gdy wyjściowy relay odrzuca strumień na podstawie polityki. To pozwala zdalnym relayom wyjściowym na nieznany wpływ poprzez mapowanie wewnętrznego adresu IP na docelową nazwę hosta odrzuconego strumienia.
Risk Assessment
Organizacja może być narażona na nieautoryzowane ujawnienie informacji o wewnętrznych adresach IP, co może prowadzić do dalszych ataków lub naruszeń prywatności użytkowników.
Recommendation
Zaleca się aktualizację Tor do najnowszej wersji, aby zapewnić prawidłowe przetwarzanie opcji konfiguracyjnych oraz zminimalizować ryzyko związane z nieautoryzowanym dostępem.

Original NVD description (English source)
Tor before 0.2.0.32 does not properly process the ClientDNSRejectInternalAddresses configuration option in situations where an exit relay issues a policy-based refusal of a stream, which allows remote exit relays to have an unknown impact by mapping an internal IP address to the destination hostname of a refused stream.
