Fixed bug (wddxdeserialize use-after-free). (CVE-2016-7413)
ext/spl/splarray.c in PHP before 5.6.26 and 7.x before 7.0.11 proceeds with SplArray unserialization without validating a return value and data type, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted serialized data.
An out-of-bounds heap read was found in pharparsezipfile due to not checking entry.uncompressedfilesize.

Fixed bug (selectcolors write out-of-bounds). (CVE-2016-7126)
Fixed bug (wddxdeserialize allows illegal memory access). (CVE-2016-7129)
ext/standard/varunserializer.c in PHP before 5.6.25 and 7.x before 7.0.10 mishandles certain invalid objects, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted serialized data that leads to a (1) destruct call or (2) magic method call.
Fixed bug (imagegammacorrect allows arbitrary write access). (CVE-2016-7127)
Double free vulnerability in the phpmbregexeregreplaceexec function in phpmbregex.c in the mbstring extension in PHP before 5.5.37, 5.6.x before 5.6.23, and 7.x before 7.0.8 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) by leveraging a callback exception.
A use after free vulnerability was discovered when PHP's garbage collection algorithm interacts with other specific PHP objects. This vulnerability has wide reaching effects like allowing the exploitation of unserialize to gain remote code execution on a target system.

/ext/phar/pharobject.c in PHP 7.0.7 and 5.6.x allows remote attackers to execute arbitrary code. NOTE: Introduced as part of an incomplete fix to CVE-2015-6833.
ext/standard/varunserializer.re in PHP 7.0.x through 7.0.22 and 7.1.x through 7.1.8 is prone to a heap use after free while unserializing untrusted data, related to improper use of the hash API for key deletion in a situation with an invalid array size. Exploitation of this issue can have an unspecified impact on the integrity of PHP.
