The Winbind nss_info extension (nsswitch/idmap_ad.c) in idmap_ad.so in Samba 3.0.25 through 3.0.25c, when the "winbind nss info" option is set to rfc2307 or sfu, grants all local users the privileges of gid 0 when the (1) RFC2307 or (2) Services for UNIX (SFU) primary group attribute is not defined.
The Samba server on Apple Mac OS X 10.3.9 and 10.4.10, when Windows file sharing is enabled, does not enforce disk quotas after dropping privileges, which allows remote authenticated users to use disk space in excess of quota.
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.
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.
smbd in Samba 3.0.6 through 3.0.23d allows remote authenticated users to cause a denial of service (memory and CPU exhaustion) by renaming a file in a way that prevents a request from being removed from the deferred open queue, which triggers an infinite loop.
Buffer overflow in the nss_winbind.so.1 library in Samba 3.0.21 through 3.0.23d, as used in the winbindd daemon on Solaris, allows attackers to execute arbitrary code via the (1) gethostbyname and (2) getipnodebyname functions.
Format string vulnerability in the afsacl.so VFS module in Samba 3.0.6 through 3.0.23d allows context-dependent attackers to execute arbitrary code via format string specifiers in a filename on an AFS file system, which is not properly handled during Windows ACL mapping.
The smdb daemon (smbd/service.c) in Samba 3.0.1 through 3.0.22 allows remote attackers to cause a denial of service (memory consumption) via a large number of share connection requests.
The winbindd daemon in Samba 3.0.21 to 3.0.21c writes the machine trust account password in cleartext in log files, which allows local users to obtain the password and spoof the server in the domain.
