Samba: >> Samba >> 3.0.25a Security Vulnerabilities
smbd in Samba before 4.4.10 and 4.5.x before 4.5.6 has a denial of service vulnerability (fd_open_atomic infinite loop with high CPU usage and memory consumption) due to wrongly handling dangling symlinks.

Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 does not require SMB signing within a DCERPC session over ncacn_np, which allows man-in-the-middle attackers to spoof SMB clients by modifying the client-server data stream.

The bundled LDAP client library in Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 does not recognize the "client ldap sasl wrapping" setting, which allows man-in-the-middle attackers to perform LDAP protocol-downgrade attacks by modifying the client-server data stream.

The NETLOGON service in Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2, when a domain controller is configured, allows remote attackers to spoof the computer name of a secure channel's endpoint, and obtain sensitive session information, by running a crafted application and leveraging the ability to sniff network traffic, a related issue to CVE-2015-0005.

The NTLMSSP authentication implementation in Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 allows man-in-the-middle attackers to perform protocol-downgrade attacks by modifying the client-server data stream to remove application-layer flags or encryption settings, as demonstrated by clearing the NTLMSSP_NEGOTIATE_SEAL or NTLMSSP_NEGOTIATE_SIGN option to disrupt LDAP security.

The shadow_copy2_get_shadow_copy_data function in modules/vfs_shadow_copy2.c in Samba 3.x and 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3 does not verify that the DIRECTORY_LIST access right has been granted, which allows remote attackers to access snapshots by visiting a shadow copy directory.

vfs.c in smbd in Samba 3.x and 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3, when share names with certain substring relationships exist, allows remote attackers to bypass intended file-access restrictions via a symlink that points outside of a share.

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.

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.
