ID CVE-2015-6834
Summary Multiple use-after-free vulnerabilities in PHP before 5.4.45, 5.5.x before 5.5.29, and 5.6.x before 5.6.13 allow remote attackers to execute arbitrary code via vectors related to (1) the Serializable interface, (2) the SplObjectStorage class, and (3) the SplDoublyLinkedList class, which are mishandled during unserialization.

However the unserialize() will still allow to use R: or r: to set references to that already freed memory.

It is possible to use-after-free attack and execute arbitrary code remotely. - CVE-2015-6836 A type confusion occurs within SOAP serialize_function_call due to an insufficient validation of the headers field. In the SoapClient's __call method, the verify_soap_headers_array check is applied only to headers retrieved from zend_parse_parameters; problem is that a few lines later, soap_headers could be updated or even replaced with values from the __default_headers object fields. - CVE-2015-6837 The XSLTProcessor class misses a few checks on the input from the libxslt library. The valuePop() function call is able to return NULL pointer and php does not check that. - CVE-2015-6838 The XSLTProcessor class misses a few checks on the input from the libxslt library. The valuePop() function call is able to return NULL pointer and php does not check that. - CVE-2015-7803 A NULL pointer dereference flaw was found in the way PHP's Phar extension parsed Phar archives. A specially crafted archive could cause PHP to crash. - CVE-2015-7804 An uninitialized pointer use flaw was found in the phar_make_dirstream() function of PHP's Phar extension. A specially crafted phar file in the ZIP format with a directory entry with a file name '/ZIP' could cause a PHP application function to crash.

    description As reported upstream, A NULL pointer dereference flaw was found in the way PHP's Phar extension parsed Phar archives. A specially crafted archive could cause PHP to crash. (CVE-2015-7803 ) A flaw was discovered in the way PHP performed object unserialization. Specially crafted input processed by the unserialize() function could cause a PHP application to crash or, possibly, execute arbitrary code. (CVE-2015-6834 , CVE-2015-6835 , CVE-2015-6836) A NULL pointer dereference flaw was found in the XSLTProcessor class in PHP. An attacker could use this flaw to cause a PHP application to crash if it performed Extensible Stylesheet Language (XSL) transformations using untrusted XSLT files and allowed the use of PHP functions to be used as XSLT functions within XSL stylesheets. (CVE-2015-6837 , CVE-2015-6838) As reported upstream, an uninitialized pointer use flaw was found in the phar_make_dirstream() function of PHP's Phar extension. A specially crafted phar file in the ZIP format with a directory entry with a file name '/ZIP' could cause a PHP application function to crash. (CVE-2015-7804)

    description According to its banner, the version of PHP running on the remote web server is 5.4.x prior to 5.4.45. It is, therefore, affected by the following vulnerabilities : - Multiple use-after-free memory errors exist related to the unserialize() function. A remote attacker can exploit these errors to execute arbitrary code. (CVE-2015-6834) - A use-after-free memory error exists related to the php_var_unserialize() function. A remote attacker, using a crafted serialize string, can exploit this to execute arbitrary code. (CVE-2015-6835) - A type confusion error exists related to the serialize_function_call() function due to improper validation of the headers field. A remote attacker can exploit this to have unspecified impact. (CVE-2015-6836) - Multiple flaws exist in the XSLTProcessor class due to improper validation of input from the libxslt library. A remote attacker can exploit thse flaws to have an unspecified impact. (CVE-2015-6837, CVE-2015-6838) - A flaw exists in the php_zip_extract_file() function in file php_zip.c due to improper sanitization of user-supplied input. An unauthenticated, remote attacker can exploit this to create arbitrary directories outside of the restricted path. Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
