PHP 7.0.x < 7.0.10 Multiple Vulnerabilities

High Nessus Plugin ID 93078

Synopsis

The version of PHP running on the remote web server is affected by multiple vulnerabilities.

Description

According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.10. It is, therefore, affected by multiple vulnerabilities :

- An unspecified flaw exists in the object_common2() function in var_unserializer.c that occurs when handling objects during deserialization. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2016-7124)

- An unspecified flaw exists in session.c that occurs when handling session names. An unauthenticated, remote attacker can exploit this to inject arbitrary data into sessions. (CVE-2016-7125)

- An integer truncation flaw exists in the select_colors() function in gd_topal.c that is triggered when handling the number of colors. An unauthenticated, remote attacker can exploit to cause a heap-based buffer overflow, resulting in the execution of arbitrary code.
(CVE-2016-7126)

- An indexing flaw exists in the imagegammacorrect() function in gd.c that occurs when handling negative gamma values. An unauthenticated, remote attacker can exploit this to write a NULL to an arbitrary memory location, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-7127)

- A flaw exists in the exif_process_IFD_in_TIFF() function in exif.c that occurs when handling TIFF image content.
An unauthenticated, remote attacker can exploit this to disclose memory contents. (CVE-2016-7128)

- A flaw exists in the php_wddx_process_data() function in wddx.c that occurs when deserializing invalid dateTime values. An unauthenticated, remote attacker can exploit this to cause a denial of service condition.
(CVE-2016-7129)

- A NULL pointer dereference flaw exists in the php_wddx_pop_element() function in wddx.c that is triggered during the handling of Base64 binary values.
An unauthenticated, remote attacker can exploit this to cause a denial of service condition. (CVE-2016-7130)

- A NULL pointer dereference flaw exists in the php_wddx_deserialize_ex() function in wddx.c that occurs during the handling of invalid XML content. An unauthenticated, remote attacker can exploit this to cause a denial of service condition. (CVE-2016-7131)

- An unspecified NULL pointer dereference flaw exists in the php_wddx_pop_element() function in wddx.c. An unauthenticated, remote attacker can exploit this to cause a denial of service condition. (CVE-2016-7132)

- An integer overflow condition exists in the zend_mm_realloc_heap() function in zend_alloc.c due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to cause a buffer overflow, resulting in a denial of service condition or the execution of arbitrary code.
(CVE-2016-7133)

- An overflow condition exists in the curl_escape() function in interface.c due to improper handling of overly long strings. An unauthenticated, remote attacker can exploit this to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-7134)

Solution

Upgrade to PHP version 7.0.10 or later.
