"ext/mysqlnd/mysqlnd_wireprotocol.c in PHP before 5.6.26 and 7.x before
7.0.11 does not verify that a BIT field has the UNSIGNED_FLAG flag,
which allows remote MySQL servers to cause a denial of service
(heap-based buffer overflow) or possibly have unspecified other impact
via crafted field metadata (CVE-2016-7412).

Use-after-free vulnerability in the wddx_stack_destroy function in
ext/wddx/wddx.c in PHP before 5.6.26 and 7.x before 7.0.11 allows
remote attackers to cause a denial of service or possibly have
unspecified other impact via a wddxPacket XML document that lacks an
end-tag for a recordset field element, leading to mishandling in a
wddx_deserialize call (CVE-2016-7413).

The ZIP signature-verification feature in PHP before 5.6.26 and 7.x
before 7.0.11 does not ensure that the uncompressed_filesize field is
large enough, which allows remote attackers to cause a denial of
service (out-of-bounds memory access) or possibly have unspecified
other impact via a crafted PHAR archive, related to ext/phar/util.c
and ext/phar/zip.c (CVE-2016-7414).

ext/intl/msgformat/msgformat_format.c in PHP before 5.6.26 and 7.x
before 7.0.11 does not properly restrict the locale length provided to
the Locale class in the ICU library, which allows remote attackers to
cause a denial of service (application crash) or possibly have
unspecified other impact via a MessageFormatter::formatMessage call
with a long first argument (CVE-2016-7416).

ext/spl/spl_array.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 (CVE-2016-7417).

The php_wddx_push_element function in ext/wddx/wddx.c in PHP before
5.6.26 and 7.x before 7.0.11 allows remote attackers to cause a denial
of service (invalid pointer access and out-of-bounds read) or possibly
have unspecified other impact via an incorrect boolean element in a
wddxPacket XML document, leading to mishandling in a wddx_deserialize
call (CVE-2016-7418)."
