PHP 5.6.x < 5.6.17 Multiple Vulnerabilities

Synopsis

Description

According to its banner, the version of PHP running on the remote host is 5.6.x prior to 5.6.17. It is, therefore, affected by multiple vulnerabilities :

- An out-of-bounds read error exists in the gdImageRotateInterpolated() function in file gd_interpolation.c when handling background colors. A remote attacker can exploit this to disclose memory contents or crash the application. (CVE-2016-1903)

- An unspecified flaw exists in file fpm_log.c in the fpm_log_write() function when handling very long HTTP requests. A local attacker can exploit this to obtain sensitive information, via access to the access log file. (CVE-2016-5114)

- A use-after-free error exists in file wddx.c in the php_wddx_pop_element() function when handling WDDX packet deserialization. A remote attacker can exploit this, by dereferencing already freed memory, to execute arbitrary code.

- A type confusion flaw exists in file xmlrpc-epi-php.c in the PHP_to_XMLRPC_worker() function. A remote attacker can exploit this to disclose memory contents, crash the application process, or have other impact.

- A type confusion flaw exists in file wddx.c when handling WDDX packet deserialization. A remote attacker can exploit this to execute arbitrary code.

- A flaw exists in file lsapilib.c when handling requests due to the LSAPI module failing to clear its secrets in child processes. A remote attacker can exploit this to gain access to memory contents, resulting in the disclosure of sensitive information.

- A flaw exists in file lsapilib.c in the parseRequest() function due to a failure to properly sanitize input passed through multiple, unspecified parameters. A remote attacker can exploit this to cause a denial of service.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.
