"Symeon Paraschoudis discovered that PHP incorrectly handled the
mkgmtime function. A remote attacker could possibly use this issue to
cause PHP to crash, resulting in a denial of service. (CVE-2014-3668)

Symeon Paraschoudis discovered that PHP incorrectly handled
unserializing objects. A remote attacker could possibly use this issue
to cause PHP to crash, resulting in a denial of service.
(CVE-2014-3669)

Otto Ebeling discovered that PHP incorrectly handled the
exif_thumbnail function. A remote attacker could use this issue to
cause PHP to crash, resulting in a denial of service, or possibly
execute arbitrary code. (CVE-2014-3670)

Francisco Alonso that PHP incorrectly handled ELF files in the
fileinfo extension. A remote attacker could possibly use this issue to
cause PHP to crash, resulting in a denial of service. (CVE-2014-3710)

It was discovered that PHP incorrectly handled NULL bytes when
processing certain URLs with the curl functions. A remote attacker
could possibly use this issue to bypass filename restrictions and
obtain access to sensitive files. (No CVE number).
