"From Red Hat Security Advisory 2016:2580 :

An update for poppler 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.

Poppler is a Portable Document Format (PDF) rendering library, used by
applications such as Evince.

Security Fix(es) :

* A heap-buffer overflow was found in the poppler library. An attacker
could create a malicious PDF file that would cause applications that
use poppler (such as Evince) to crash or, potentially, execute
arbitrary code when opened. (CVE-2015-8868)

Additional Changes :

For detailed information on changes in this release, see the Red Hat
Enterprise Linux 7.3 Release Notes linked from the References section."

Impact :

    A remote attacker could entice a user to open a specially crafted PDF
      using Poppler, possibly resulting in execution of arbitrary code with the
      privileges of the process or a Denial of Service condition.
  
Workaround :
