Security Fix(es):

* A flaw was found in the way certain error conditions were handled by
bzread() function in PHP. An attacker could use this flaw to upload a
specially crafted bz2 archive which, when parsed via the vulnerable
function, could cause the application to crash or execute arbitrary code
with the permissions of the user running the PHP application.
(CVE-2016-5399)

* An integer overflow flaw, leading to a heap-based buffer overflow was
found in the imagecreatefromgd2() function of PHP's gd extension. A remote
attacker could use this flaw to crash a PHP application or execute
arbitrary code with the privileges of the user running that PHP
application using gd via a specially crafted GD2 image. (CVE-2016-5766)

* An integer overflow flaw, leading to a heap-based buffer overflow was
found in the gdImagePaletteToTrueColor() function of PHP's gd extension. A
remote attacker could use this flaw to crash a PHP application or execute
arbitrary code with the privileges of the user running that PHP
application using gd via a specially crafted image buffer. (CVE-2016-5767)

* A double free flaw was found in the mb_ereg_replace_callback() function
of php which is used to perform regex search. This flaw could possibly
cause a PHP application to crash. (CVE-2016-5768)
