Synopsis

Description

According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.11. It is, therefore, affected by multiple vulnerabilities :

- An heap buffer overflow condition exists in the php_mysqlnd_rowp_read_text_protocol_aux() function within file ext/mysqlnd/mysqlnd_wireprotocol.c due to a failure to verify that a BIT field has the UNSIGNED_FLAG flag. An unauthenticated, remote attacker can exploit this, via specially crafted field metadata, to cause a denial of service condition. (CVE-2016-7412)

- A use-after-free error exists in the wddx_stack_destroy() function within file ext/wddx/wddx.c when deserializing recordset elements. An unauthenticated, remote attacker can exploit this, via a specially crafted wddxPacket XML document, to cause a denial of service condition. (CVE-2016-7413)

- An out-of-bounds access error exists in the phar_parse_zipfile() function within file ext/phar/zip.c due to a failure to ensure that the uncompressed_filesize field is large enough. An unauthenticated, remote attacker can exploit this, via a specially crafted archive, to cause a denial of service condition. (CVE-2016-7414)

- A stack-based buffer overflow condition exists in the ICU4C library, specifically within file common/locid.cpp in the msgfmt_format_message() function, due to a failure to properly restrict the locale length provided to the Locale class. An unauthenticated, remote attacker can exploit this, via a long first argument to a MessageFormatter::formatMessage() function call, to cause a denial of service condition. (CVE-2016-7416)

- A flaw exists in the spl_array_get_dimension_ptr_ptr() function within file ext/spl/spl_array.c due to a failure to properly validate the return value and data type when deserializing SplArray. An unauthenticated, remote attacker can exploit this, via specially crafted serialized data, to cause a denial of service condition. (CVE-2016-7417)

- An out-of-bounds read error exists in the php_wddx_push_element() function within file ext/wddx/wddx.c when handling an incorrect boolean element, which leads to mishandling the wddx_deserialize() call. An unauthenticated, remote attacker can exploit this, via a specially crafted wddxPacket XML document, to cause a denial of service condition. (CVE-2016-7418)

- An out-of-bounds access error exists in the phar_parse_tarfile() function within file ext/phar/tar.c when handling the verification of signatures. An unauthenticated, remote attacker can exploit this to cause an unspecified impact.

Note that this software is reportedly affected by other vulnerabilities as well that have not been fixed yet in version 7.0.13.
