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.

Samba 4.x before 4.0.4, when configured as an Active Directory domain controller, uses world-writable permissions on non-default CIFS shares, which allows remote authenticated users to read, modify, create, or delete arbitrary files via standard filesystem operations.

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.

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.

Samba 4.0.x before 4.0.1, in certain Active Directory domain-controller configurations, does not properly interpret Access Control Entries that are based on an objectClass, which allows remote authenticated users to bypass intended restrictions on modifying LDAP directory objects by leveraging (1) objectClass access by a user, (2) objectClass access by a group, or (3) write access to an attribute.

The (1) CreateAccount, (2) OpenAccount, (3) AddAccountRights, and (4) RemoveAccountRights LSA RPC procedures in smbd in Samba 3.4.x before 3.4.17, 3.5.x before 3.5.15, and 3.6.x before 3.6.5 do not properly restrict modifications to the privileges database, which allows remote authenticated users to obtain the "take ownership" privilege via an LSA connection.

The RPC code generator in Samba 3.x before 3.4.16, 3.5.x before 3.5.14, and 3.6.x before 3.6.4 does not implement validation of an array length in a manner consistent with validation of array memory allocation, which allows remote attackers to execute arbitrary code via a crafted RPC call.

Heap-based buffer overflow in process.c in smbd in Samba 3.0, as used in the file-sharing service on the BlackBerry PlayBook tablet before 2.0.0.7971 and other products, allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a Batched (aka AndX) request that triggers infinite recursion.

Memory leak in smbd in Samba 3.6.x before 3.6.3 allows remote attackers to cause a denial of service (memory and CPU consumption) by making many connection requests.
