The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2016-023:01 advisory.

    Samba is the standard Windows interoperability suite of programs for Linux and Unix.
    Security issues fixed with this release:
    CVE-2015-3223     The ldb_wildcard_compare function in ldb_match.c in ldb before 1.1.24,     as used in the AD LDAP server in Samba 4.x before 4.1.22, 4.2.x before     4.2.7, and 4.3.x before 4.3.3, mishandles certain zero values, which     allows remote attackers to cause a denial of service (infinite loop)     via crafted packets.
    CVE-2015-5252     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.
    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, libsmb_server.c, and smbXcli_base.c.
    CVE-2015-5299     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.
    CVE-2015-7540     The LDAP server in the AD domain controller in Samba 4.x before 4.1.22     does not check return values to ensure successful ASN.1 memory     allocation, which allows remote attackers to cause a denial of service     (memory consumption and daemon crash) via crafted packets.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Update to Samba 4.3.3 (security release)

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote NewStart CGSL host, running version MAIN 6.02, has samba packages installed that are affected by multiple vulnerabilities:

  - Multiple heap-based buffer overflows in the NDR parsing in smbd in Samba 3.0.0 through 3.0.25rc3 allow     remote attackers to execute arbitrary code via crafted MS-RPC requests involving (1) DFSEnum     (netdfs_io_dfs_EnumInfo_d), (2) RFNPCNEX (smb_io_notify_option_type_data), (3) LsarAddPrivilegesToAccount     (lsa_io_privilege_set), (4) NetSetFileSecurity (sec_io_acl), or (5) LsarLookupSids/LsarLookupSids2     (lsa_io_trans_names). (CVE-2007-2446)

  - 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. (CVE-2007-2447)

  - Heap-based buffer overflow in the receive_smb_raw function in util/sock.c in Samba 3.0.0 through 3.0.29     allows remote attackers to execute arbitrary code via a crafted SMB response. (CVE-2008-1105)

  - Samba 3.4 before 3.4.2, 3.3 before 3.3.8, 3.2 before 3.2.15, and 3.0.12 through 3.0.36, as used in the SMB     subsystem in Apple Mac OS X 10.5.8 when Windows File Sharing is enabled, Fedora 11, and other operating     systems, does not properly handle errors in resolving pathnames, which allows remote authenticated users     to bypass intended sharing restrictions, and read, create, or modify files, in certain circumstances     involving user accounts that lack home directories. (CVE-2009-2813)

  - smbd in Samba 3.0 before 3.0.37, 3.2 before 3.2.15, 3.3 before 3.3.8, and 3.4 before 3.4.2 allows remote     authenticated users to cause a denial of service (infinite loop) via an unanticipated oplock break     notification reply packet. (CVE-2009-2906)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Several vulnerabilities have been discovered in Samba, a SMB/CIFS file, print, and login server for Unix. The Common Vulnerabilities and Exposures project identifies the following issues :

  - CVE-2015-3223     Thilo Uttendorfer of Linux Information Systems AG     discovered that a malicious request can cause the Samba     LDAP server to hang, spinning using CPU. A remote     attacker can take advantage of this flaw to mount a     denial of service.

  - CVE-2015-5252     Jan 'Yenya' Kasprzak and the Computer Systems Unit team     at Faculty of Informatics, Masaryk University discovered     that insufficient symlink verification could allow data     access outside an exported share path.

  - CVE-2015-5296     Stefan Metzmacher of SerNet discovered that Samba does     not ensure that signing is negotiated when creating an     encrypted client connection to a server. This allows a     man-in-the-middle attacker to downgrade the connection     and connect using the supplied credentials as an     unsigned, unencrypted connection.

  - CVE-2015-5299     It was discovered that a missing access control check in     the VFS shadow_copy2 module could allow unauthorized     users to access snapshots.

  - CVE-2015-5330     Douglas Bagnall of Catalyst discovered that the Samba     LDAP server is vulnerable to a remote memory read     attack. A remote attacker can obtain sensitive     information from daemon heap memory by sending crafted     packets and then either read an error message, or a     database value.

  - CVE-2015-7540     It was discovered that a malicious client can send     packets that cause the LDAP server provided by the AD DC     in the samba daemon process to consume unlimited memory     and be terminated.

  - CVE-2015-8467     Andrew Bartlett of the Samba Team and Catalyst     discovered that a Samba server deployed as an AD DC can     expose Windows DCs in the same domain to a denial of     service via the creation of multiple machine accounts.
    This issue is related to the MS15-096 / CVE-2015-2535     security issue in Windows.

A missing access control flaw was found in Samba. A remote, authenticated attacker could use this flaw to view the current snapshot on a Samba share, despite not having DIRECTORY_LIST access rights.

An access flaw was found in the way Samba verified symbolic links when creating new files on a Samba share. A remote attacker could exploit this flaw to gain access to files outside of Samba's share path.

A memory-read flaw was found in the way the libldb library processed LDB DN records with a null byte. An authenticated, remote attacker could use this flaw to read heap-memory pages from the server.

A man-in-the-middle vulnerability was found in the way 'connection signing' was implemented by Samba. A remote attacker could use this flaw to downgrade an existing Samba client connection and force the use of plain text.

The Rocky Linux 8.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ ciqsa-2026_0027 advisory.

    This advisory aggregates security fixes for the samba SRPM in CIQ LTS 8.6. It addresses 74 CVEs:
    CVE-2008-4314, CVE-2018-1050, CVE-2015-7560, CVE-2013-4475, CVE-2019-14907, and 69 more.

Tenable has extracted the preceding description block directly from the CIQ security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
