"Thomas Jarosch discovered that PHP incorrectly limited recursion in
the fileinfo extension. A remote attacker could possibly use this
issue to cause PHP to consume resources or crash, resulting in a
denial of service. (CVE-2014-8117)

S. Paraschoudis discovered that PHP incorrectly handled memory in the
enchant binding. A remote attacker could use this issue to cause PHP
to crash, resulting in a denial of service, or possibly execute
arbitrary code. (CVE-2014-9705)

Taoguang Chen discovered that PHP incorrectly handled unserializing
objects. A remote attacker could use this issue to cause PHP to crash,
resulting in a denial of service, or possibly execute arbitrary code.
(CVE-2015-0273)

It was discovered that PHP incorrectly handled memory in the phar
extension. A remote attacker could use this issue to cause PHP to
