CVE-2015-5296

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 supports connections that are encrypted but unsigned, which allows man-in-the-middle attackers to conduct encrypted-to-unencrypted downgrade attacks by modifying the client-server data stream, related to clidfs.c,...

Samba client requesting encryption vulnerable

Description Versions of Samba from 3.2.0 to 4.3.2 inclusive do not ensure that signing is negotiated when creating an encrypted client connection to a server. Without this a man-in-the-middle attack could downgrade the connection and connect using the supplied credentials as an unsigned,...

Missing access control check in shadow copy

Description All versions of Samba from 3.2.0 to 4.3.2 inclusive are vulnerable to a missing access control check in the vfsshadowcopy2 module. When looking for the shadow copy directory under the share path the current accessing user should have DIRECTORYLIST access rights in order to view the...

Denial of service attack against Windows

Description Samba, operating as an AD DC, is sometimes operated in a domain with a mix of Samba and Windows Active Directory Domain Controllers. All versions of Samba from 4.0.0 to 4.3.2 inclusive, when deployed as an AD DC in the same domain with Windows DCs, could be used to override the...

Insufficient symlink verification in smbd.

Description All versions of Samba from 3.0.0 to 4.3.2 inclusive are vulnerable to a bug in symlink verification, which under certain circumstances could allow client access to files outside the exported share path. If a Samba share is configured with a path that shares a common path prefix with...
