Published:		16.05.2007
Source:		BUGTRAQ
SecurityVulns ID:		7713
Type:		remote
Level:		7/10
Description:		Multiple heap based buffer overflows, invalid SID to uid translation privilege escalation, shell characters problem.

Affected:		SAMBA : Samba 3.0
CVE:		CVE-2007-2447 (The MS-RPC functionality in smbd in Samba 3.0.0 through 3.0.25rc3 allows remote attackers to execute arbitrary commands via shell metacharacters involving the (1) SamrChangePassword function, when the "username map script" smb.conf option is enabled, and allows remote authenticated users to execute commands via shell metacharacters involving other MS-RPC functions in the (2) remote printer and (3) file share management.)
		CVE-2007-2446 (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).)
		CVE-2007-2444 (Logic error in the SID/Name translation functionality in smbd in Samba 3.0.23d through 3.0.25pre2 allows local users to gain temporary privileges and execute SMB/CIFS protocol operations via unspecified vectors that cause the daemon to transition to the root user.)
