This update for php5 fixes the following issues:

• CVE-2013-7456: imagescale out-of-bounds read (bnc#982009).
• CVE-2016-5093: get_icu_value_internal out-of-bounds read (bnc#982010).
• CVE-2016-5094: Don’t create strings with lengths outside int range
  (bnc#982011).
• CVE-2016-5095: Don’t create strings with lengths outside int range
  (bnc#982012).
• CVE-2016-5096: int/size_t confusion in fread (bsc#982013).
• CVE-2016-5114: fpm_log.c memory leak and buffer overflow (bnc#982162).
• CVE-2015-8877: The gdImageScaleTwoPass function in gd_interpolation.c in
  the GD Graphics Library (aka libgd), as used in PHP, used inconsistent
  allocate and free approaches, which allowed remote attackers to cause a
  denial of service (memory consumption) via a crafted call, as
  demonstrated by a call to the PHP imagescale function (bsc#981061).
• CVE-2015-8876: Zend/zend_exceptions.c in PHP did not validate certain
  Exception objects, which allowed remote attackers to cause a denial of
  service (NULL pointer dereference and application crash) or trigger
  unintended method execution via crafted serialized data (bsc#981049).
• CVE-2015-8879: The odbc_bindcols function in ext/odbc/php_odbc.c in PHP
  mishandled driver behavior for SQL_WVARCHAR columns, which allowed
  remote attackers to cause a denial of service (application crash) in
  opportunistic circumstances by leveraging use of the odbc_fetch_array
  function to access a certain type of Microsoft SQL Server table Aliased:
  (bsc#981050).
• CVE-2015-4116: Use-after-free vulnerability in the spl_ptr_heap_insert
  function in ext/spl/spl_heap.c in PHP allowed remote attackers to
  execute arbitrary code by triggering a failed SplMinHeap::compare
  operation (bsc#980366).
• CVE-2015-8874: Stack consumption vulnerability in GD in PHP allowed
  remote attackers to cause a denial of service via a crafted
  imagefilltoborder call (bsc#980375).
• CVE-2015-8873: Stack consumption vulnerability in Zend/zend_exceptions.c
  in PHP allowed remote attackers to cause a denial of service
  (segmentation fault) via recursive method calls (bsc#980373).
• CVE-2016-3074: Integer signedness error in GD Graphics Library (aka
  libgd or libgd2) allowed remote attackers to cause a denial of service
  (crash) or potentially execute arbitrary code via crafted compressed gd2
  data, which triggers a heap-based buffer overflow (bsc#976775).
