Heap-based buffer overflow in the dcerpc_read_ncacn_packet_done function in librpc/rpc/dcerpc_util.c in winbindd in Samba 3.x before 3.6.22, 4.0.x before 4.0.13, and 4.1.x before 4.1.3 allows remote AD domain controllers to execute arbitrary code via an invalid fragment length in a DCE-RPC packet.

The winbind_name_list_to_sid_string_list function in nsswitch/pam_winbind.c in Samba through 4.1.2 handles invalid require_membership_of group names by accepting authentication by any user, which allows remote authenticated users to bypass intended access restrictions in opportunistic circumstances by leveraging an administrator's pam_winbind configuration-file mistake.

Samba 3.2.x through 3.6.x before 3.6.20, 4.0.x before 4.0.11, and 4.1.x before 4.1.1, when vfs_streams_depot or vfs_streams_xattr is enabled, allows remote attackers to bypass intended file restrictions by leveraging ACL differences between a file and an associated alternate data stream (ADS).

Integer overflow in the read_nttrans_ea_list function in nttrans.c in smbd in Samba 3.x before 3.5.22, 3.6.x before 3.6.17, and 4.x before 4.0.8 allows remote attackers to cause a denial of service (memory consumption) via a malformed packet.

The SMB2 implementation in Samba 3.6.x before 3.6.6, as used on the IBM Storwize V7000 Unified 1.3 before 1.3.2.3 and 1.4 before 1.4.0.1 and possibly other products, does not properly enforce CIFS share attributes, which allows remote authenticated users to (1) write to a read-only share; (2) trigger data-integrity problems related to the oplock, locking, coherency, or leases attribute; or (3) have an unspecified impact by leveraging incorrect handling of the browseable or "hide unreadable" parameter.

Cross-site request forgery (CSRF) vulnerability in the Samba Web Administration Tool (SWAT) in Samba 3.x before 3.5.21, 3.6.x before 3.6.12, and 4.x before 4.0.2 allows remote attackers to hijack the authentication of arbitrary users by leveraging knowledge of a password and composing requests that perform SWAT actions.

The Samba Web Administration Tool (SWAT) in Samba 3.x before 3.5.21, 3.6.x before 3.6.12, and 4.x before 4.0.2 allows remote attackers to conduct clickjacking attacks via a (1) FRAME or (2) IFRAME element.
