This update for php7 fixes several issues.

These security issues were fixed:

- CVE-2017-12932: Prevent 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 could have had an
unspecified impact on the integrity of PHP (bsc#1054432).
- CVE-2017-12934: Prevent heap use after free while unserializing untrusted
data, related to the zval_get_type function in Zend/zend_types.h.
Exploitation of this issue could have had an unspecified impact on the
integrity of PHP (bsc#1054408).
- CVE-2017-12933: The finish_nested_data function in
ext/standard/var_unserializer.re was prone to a buffer over-read while
unserializing untrusted data. Exploitation of this issue could have had an
unspecified impact on the integrity of PHP (bsc#1054430)

These non-security issues were fixed:

- bsc#1057104: php7-devel now requires php7-pear
- bsc#1057845: Fixed namespace encapsulation of imported classes/functions/constants
