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 7.0.8. It is, therefore, affected by multiple vulnerabilities :- An invalid free flaw exists in the phar_extract_file() function within file ext/phar/phar_object.c that allows an unauthenticated, remote attacker to have an unspecified impact. (CVE-2016-4473)
- 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. (CVE-2016-5766)
- An integer overflow condition exists in the gdImagePaletteToTrueColor() function within file ext/gd/libgd/gd.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. (CVE-2016-5767)
- A double-free error exists in the
_php_mb_regex_ereg_replace_exec() function within file ext/mbstring/php_mbregex.c when handling a failed callback execution. 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.
