The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2016:0010 advisory.

    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 denial of service flaw was found in the LDAP server provided by the AD DC     in the Samba process daemon. A remote attacker could exploit this flaw by     sending a specially crafted packet, which could cause the server to consume     an excessive amount of memory and crash. (CVE-2015-7540)

    Multiple buffer over-read flaws were found in the way Samba handled     malformed inputs in certain encodings. An authenticated, remote attacker     could possibly use these flaws to disclose portions of the server memory.
    (CVE-2015-5330)

    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 flaws, and Douglas Bagnall as the original     reporter of CVE-2015-5330.

    All samba4 users are advised to upgrade to these updated packages, which     contain backported patches to correct these issues. After installing this     update, the smb service will be restarted automatically.
