Description
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).
Public exploit
An exploit or proof of concept is public: anyone can try it against an unpatched system. The public collections list 5 Metasploit modules and 4 Exploit-DB entries for it.
