"According to the versions of the libXpm, libXdmcp, libICE packages
installed, the EulerOS installation on the remote host is affected by
the following vulnerabilities :

  - An integer overflow flaw leading to a heap-based buffer
    overflow was found in libXpm. An attacker could use
    this flaw to crash an application using libXpm via a
    specially crafted XPM file. (CVE-2016-10164)

  - It was discovered that libXdmcp used weak entropy to
    generate session keys. On a multi-user system using
    xdmcp, a local attacker could potentially use
    information available from the process list to brute
    force the key, allowing them to hijack other users'
    sessions. (CVE-2017-2625)

  - It was discovered that libICE used a weak entropy to
    generate keys. A local attacker could potentially use
    this flaw for session hijacking using the information
    available from the process list. (CVE-2017-2626)

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