    description A stack consumption vulnerability in GD in PHP allows remote attackers to cause a denial of service via a crafted imagefilltoborder call. (CVE-2015-8874) An integer overflow, leading to a heap-based buffer overflow was found in the imagecreatefromgd2() function of PHP's gd extension. A remote attacker could use this flaw to crash a PHP application or execute arbitrary code with the privileges of the user running that PHP application, using gd via a specially crafted GD2 image. (CVE-2016-5766) An integer overflow, leading to a heap-based buffer overflow was found in the gdImagePaletteToTrueColor() function of PHP's gd extension. A remote attacker could use this flaw to crash a PHP application or execute arbitrary code with the privileges of the user running that PHP application, using gd via a specially crafted image buffer. (CVE-2016-5767) A double free flaw was found in the mb_ereg_replace_callback() function of php which is used to perform regex search. This flaw could possibly cause a PHP application to crash. (CVE-2016-5768) The mcrypt_generic() and mdecrypt_generic() functions are prone to integer overflows, resulting in a heap-based overflow. A remote attacker could use this flaw to crash a PHP application or execute arbitrary code with the privileges of the user running that PHP application. (CVE-2016-5769) A type confusion issue was found in the SPLFileObject fread() function. A remote attacker able to submit a specially crafted input to a PHP application, which uses this function, could use this flaw to execute arbitrary code with the privileges of the user running that PHP application. (CVE-2016-5770) A use-after-free vulnerability that can occur when calling unserialize() on untrusted input was discovered. A remote attacker could use this flaw to crash a PHP application or execute arbitrary code with the privileges of the user running that PHP application if the application unserializes untrusted input. (CVE-2016-5771 , CVE-2016-5773) A double free can occur in wddx_deserialize() when trying to deserialize malicious XML input from user's request. This flaw could possibly cause a PHP application to crash. (CVE-2016-5772) It was discovered that PHP did not properly protect against the HTTP_PROXY variable name clash. A remote attacker could possibly use this flaw to redirect HTTP requests performed by a PHP script to an attacker-controlled proxy via a malicious HTTP request. (CVE-2016-5385) (Updated on 2016-08-17: CVE-2016-5385 was fixed in this release but was not previously part of this errata)

    description According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.8. It is, therefore, affected by multiple vulnerabilities : - An integer overflow condition exists in the _gd2GetHeader() function in file ext/gd/libgd/gd_gd2.c due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code.

An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2016-5768) - An integer overflow condition exists within file ext/mcrypt/mcrypt.c due to improper validation of user-supplied input when handling data values. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-5769) - An integer overflow condition exists within file ext/spl/spl_directory.c, triggered by an int/size_t type confusion error, that allows an unauthenticated, remote attacker to have an unspecified impact. (CVE-2016-5770) - A use-after-free error exists in the garbage collection algorithm within file ext/spl/spl_array.c. An unauthenticated, remote attacker can exploit this to dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2016-5771) - A double-free error exists in the php_wddx_process_data() function within file ext/wddx/wddx.c when handling specially crafted XML content. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2016-5772) - A use-after-free error exists in the garbage collection algorithm within file ext/zip/php_zip.c. An unauthenticated, remote attacker can exploit this to dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2016-5773) - An integer overflow condition exists in the json_decode() and json_utf8_to_utf16() functions within file ext/standard/php_smart_str.h due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. - An out-of-bounds read error exists in the pass2_no_dither() function within file ext/gd/libgd/gd_topal.c that allows an unauthenticated, remote attacker to cause a denial of service condition or disclose memory contents. - An integer overflow condition exists within file ext/standard/string.c when handling string lengths due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to have an unspecified impact. - A NULL pointer dereference flaw exists in the _gdScaleVert() function within file ext/gd/libgd/gd_interpolation.c that is triggered when handling _gdContributionsCalc return values. An unauthenticated, remote attacker can exploit this to cause a denial of service condition. - An integer overflow condition exists in the nl2br() function within file ext/standard/string.c when handling new_length values due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to have an unspecified impact. - An integer overflow condition exists in multiple functions within file ext/standard/string.c when handling string values due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to have an unspecified impact. Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
