"From Red Hat Security Advisory 2017:3221 :

An update for php 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.

PHP is an HTML-embedded scripting language commonly used with the
Apache HTTP Server.

Security Fix(es) :

* A NULL pointer dereference flaw was found in libgd. An attacker
could use a specially crafted .gd2 file to cause an application linked
with libgd to crash, leading to denial of service. (CVE-2016-10167)

* An integer overflow flaw, leading to a heap-based buffer overflow
was found in the way libgd read some specially crafted gd2 files. A
remote attacker could use this flaw to crash an application compiled
with libgd or in certain cases execute arbitrary code with the
privileges of the user running that application. (CVE-2016-10168)"
