Security update for php7 (important)

This update for php7 fixes the following security issues:

• CVE-2016-7480: The SplObjectStorage unserialize implementation in
  ext/spl/spl_observer.c in PHP did not verify that a key is an object,
  which allowed remote attackers to execute arbitrary code or cause a
  denial
  of service (uninitialized memory access) via crafted serialized data.
  (bsc#1019568)
• CVE-2017-5340: Zend/zend_hash.c in PHP mishandled certain cases that
  require large array allocations, which allowed remote attackers to
  execute arbitrary code or cause a denial of service (integer overflow,
  uninitialized memory access, and use of arbitrary destructor function
  pointers) via crafted serialized data. (bsc#1019570)
• CVE-2016-7479: In all versions of PHP 7, during the unserialization
  process, resizing the ‘properties’ hash table of a serialized object may
  have lead to use-after-free. A remote attacker may exploit this bug to
  gain arbitrary code execution. (bsc#1019547)
• CVE-2016-7478: Zend/zend_exceptions.c in PHP allowed remote attackers to
  cause a denial of service (infinite loop) via a crafted Exception object
  in serialized data, a related issue to CVE-2015-8876. (bsc#1019550)
• CVE-2016-10159: Integer overflow in the phar_parse_pharfile function in
  ext/phar/phar.c in PHP allowed remote attackers to cause a denial
  of service (memory consumption or application crash) via a truncated
  manifest entry in a PHAR archive. (bsc#1022255)
• CVE-2016-10160: Off-by-one error in the phar_parse_pharfile function in
  ext/phar/phar.c in PHP allowed remote attackers to cause a denial
  of service (memory corruption) or possibly execute arbitrary code via a
  crafted PHAR archive with an alias mismatch. (bsc#1022257)
• CVE-2016-10161: The object_common1 function in
  ext/standard/var_unserializer.c in PHP allowed remote attackers to cause
  a denial of service (buffer over-read and application crash) via crafted
  serialized data that is mishandled in a finish_nested_data call.
  (bsc#1022260)
• CVE-2016-10162: The php_wddx_pop_element function in ext/wddx/wddx.c in
  PHP 7 allowed remote attackers to cause a denial of service (NULL
  pointer dereference and application crash) via an inapplicable class
  name in a wddxPacket XML document, leading to mishandling in a
  wddx_deserialize call. (bsc#1022262)
• CVE-2016-10166: A potential unsigned underflow in gd interpolation
  functions could lead to memory corruption in the PHP gd module
  (bsc#1022263)
• CVE-2016-10167: A denial of service problem in gdImageCreateFromGd2Ctx()
  could lead to php out of memory even on small files. (bsc#1022264)
• CVE-2016-10168: A signed integer overflow in the gd module could lead to
  memory corruption (bsc#1022265)
• CVE-2016-9138: PHP mishandled property modification during __wakeup
  processing, which allows remote attackers to cause a denial of service
  or possibly have unspecified other impact via crafted serialized data,
  as demonstrated by Exception::__toString with DateInterval::__wakeup.
