The remote host is affected by the vulnerability described in GLSA-201701-72 (libXpm: Remote execution of arbitrary code)

    An integer overflow was discovered in libXpm&rsquo;s src/CrDatFrI.c file.
      On 64 bit systems, this allows an overflow to occur on 32 bit integers       while parsing XPM extensions in a file.
  Impact :

    A remote attacker, by enticing a user to process a specially crafted XPM       file, could execute arbitrary code with the privileges of the process or       cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2017-1865 advisory.

    - Use libbsd for randoms (CVE-2017-2626, rhbz#1427715)
    - Use libbsd for randoms (CVE-2017-2625, rhbz#1427716)
    - fixes CVE-2016-5407
    - fixes CVE-2016-7953

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.

An update 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.

The X11 (Xorg) libraries provide library routines that are used within all X Window applications.

The following packages have been upgraded to a later upstream version:
libX11 (1.6.5), libXaw (1.0.13), libXdmcp (1.1.2), libXfixes (5.0.3), libXfont (1.5.2), libXi (1.7.9), libXpm (3.5.12), libXrandr (1.5.1), libXrender (0.9.10), libXt (1.1.5), libXtst (1.2.3), libXv (1.0.11), libXvMC (1.0.10), libXxf86vm (1.1.4), libdrm (2.4.74), libepoxy (1.3.1), libevdev (1.5.6), libfontenc (1.1.3), libvdpau (1.1.1), libwacom (0.24), libxcb (1.12), libxkbfile (1.0.9), mesa (17.0.1), mesa-private-llvm (3.9.1), xcb-proto (1.12), xkeyboard-config (2.20), xorg-x11-proto-devel (7.7).

Security Fix(es) :

* 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)

Red Hat would like to thank Eric Sesterhenn (X41 D-Sec GmbH) for reporting CVE-2017-2625 and CVE-2017-2626.
