Updated samba packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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

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. (CVE-2015-5296)

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. (CVE-2015-5299)

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.
(CVE-2015-5252)

Red Hat would like to thank the Samba project for reporting these issues. Upstream acknowledges Stefan Metzmacher of the Samba Team and Sernet.de as the original reporters of CVE-2015-5296, partha@exablox.com as the original reporter of CVE-2015-5299, Jan 'Yenya' Kasprzak and the Computer Systems Unit team at Faculty of Informatics, Masaryk University as the original reporters of CVE-2015-5252.

All samba users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing this update, the smb service will be restarted automatically.

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.
