    - resolves: #1614265 - Fix CVE-2018-1139
    - resolves: #1614269 - Fix CVE-2018-10858

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

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

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3738-1 advisory.

    Svyatoslav Phirsov discovered that the Samba libsmbclient library incorrectly handled extra long     filenames. A malicious server could use this issue to cause Samba to crash, resulting in a denial of     service, or possibly execute arbitrary code. (CVE-2018-10858)

    Volker Mauel discovered that Samba incorrectly handled database output. When used as an Active Directory     Domain Controller, a remote authenticated attacker could use this issue to cause Samba to crash, resulting     in a denial of service. This issue only affected Ubuntu 18.04 LTS. (CVE-2018-10918)

    Phillip Kuhrt discovered that the Samba LDAP server incorrectly handled certain confidential attribute     values. A remote authenticated attacker could possibly use this issue to obtain certain sensitive     information. (CVE-2018-10919)

    Vivek Das discovered that Samba incorrectly handled NTLMv1 being explicitly disabled on the server. A     remote user could possibly be authenticated using NTLMv1, contrary to expectations. This issue only     affected Ubuntu 18.04 LTS. (CVE-2018-1139)

Update to Samba 4.7.9, Security fix for CVE-2018-1139, CVE-2018-1140, CVE-2018-10858, CVE-2018-10918, CVE-2018-10919

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

According to the version of the samba packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - A flaw was found in the way samba allowed the use of     weak NTLMv1 authentication even when NTLMv1 was     explicitly disabled. A man-in-the-middle attacker could     use this flaw to read the credential and other details     passed between the samba server and     client.(CVE-2019-1139)

According to the version of the samba packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :

  - A flaw was found in the way samba allowed the use of     weak NTLMv1 authentication even when NTLMv1 was     explicitly disabled. A man-in-the-middle attacker could     use this flaw to read the credential and other details     passed between the samba server and     client.(CVE-2018-1139)

An update for samba is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Samba is an open source implementation of the Server Message Block (SMB) protocol and the related Common Internet File System (CIFS) protocol, which allow PC-compatible machines to share files, printers, and various information.

The following packages have been upgraded to a later upstream version:
samba (4.8.3). (BZ#1558560)

Security Fix(es) :

* samba: Weak authentication protocol regression (CVE-2018-1139)

* samba: Insufficient input validation in libsmbclient (CVE-2018-10858)

* samba: NULL pointer dereference in printer server process (CVE-2018-1050)

For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

Red Hat would like to thank the Samba project for reporting CVE-2018-1050. The CVE-2018-1139 issue was discovered by Vivek Das (Red Hat).

Additional Changes :

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.
