CVE-2007-2446
HighSummary
Wiele przepełnień bufora na stercie w analizie NDR w smbd w Samba w wersjach od 3.0.0 do 3.0.25rc3 umożliwia zdalnym atakującym wykonanie dowolnego kodu poprzez spreparowane żądania MS-RPC. Dotyczy to m.in. funkcji DFSEnum, RFNPCNEX, LsarAddPrivilegesToAccount, NetSetFileSecurity oraz LsarLookupSids.
Risk Assessment
Podatność ta stwarza poważne ryzyko dla organizacji, ponieważ umożliwia zdalne wykonanie kodu, co może prowadzić do przejęcia kontroli nad systemem. Atakujący mogą wykorzystać tę lukę do wprowadzenia złośliwego oprogramowania lub kradzieży danych.
Recommendation
Zaleca się aktualizację do najnowszej wersji Samba, aby usunąć tę podatność. Dodatkowo, warto monitorować ruch sieciowy w celu wykrywania podejrzanych żądań MS-RPC.

Original NVD description (English source)
Multiple heap-based buffer overflows in the NDR parsing in smbd in Samba 3.0.0 through 3.0.25rc3 allow remote attackers to execute arbitrary code via crafted MS-RPC requests involving (1) DFSEnum (netdfs_io_dfs_EnumInfo_d), (2) RFNPCNEX (smb_io_notify_option_type_data), (3) LsarAddPrivilegesToAccount (lsa_io_privilege_set), (4) NetSetFileSecurity (sec_io_acl), or (5) LsarLookupSids/LsarLookupSids2 (lsa_io_trans_names).
