The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2789 advisory.

    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.

    Security Fix(es):

    * A race condition was found in samba server. A malicious samba client could use this flaw to access files     and directories in areas of the server file system not exported under the share definitions.
    (CVE-2017-2619)

    * It was found that samba did not enforce SMB signing when certain configuration options were enabled. A     remote attacker could launch a man-in-the-middle attack and retrieve information in plain-text.
    (CVE-2017-12150)

    * An information leak flaw was found in the way SMB1 protocol was implemented by Samba. A malicious client     could use this flaw to dump server memory contents to a file on the samba share or to a shared printer,     though the exact area of server memory cannot be controlled by the attacker. (CVE-2017-12163)

    Red Hat would like to thank the Samba project for reporting CVE-2017-2619 and CVE-2017-12150 and Yihan     Lian and Zhibin Hu (Qihoo 360 GearTeam), Stefan Metzmacher (SerNet), and Jeremy Allison (Google) for     reporting CVE-2017-12163. Upstream acknowledges Jann Horn (Google) as the original reporter of     CVE-2017-2619; and Stefan Metzmacher (SerNet) as the original reporter of CVE-2017-12150.
