"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)

preceding description block directly from the corresponding Red Hat
security advisory. Virtuozzo provides no description for VZLSA
advisories. Tenable has attempted to automatically clean and format
it as much as possible without introducing additional issues.");
