Descriptions

PHP before 5.6.7 might allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via an unexpected data type, related to "type confusion" issues in (1) ext/soap/php_encoding.c, (2) ext/soap/php_http.c, and (3) ext/soap/soap.c, a different issue than CVE-2015-4600.

PHP en versiones anteriores a 5.6.7 podría permitir a atacantes remotos provocar una denegación de servicio (caída de aplicación) o posiblemente ejecuar código arbitrario a través de un tipo de dato no esperado, relacionado con casos "type confusion" en (1) ext/soap/php_encoding.c, (2) ext/soap/php_http.c y (3) ext/soap/soap.c, un caso diferente a CVE-2015-4600.

Multiple flaws were discovered in the way PHP's Soap extension performed object unserialization. Specially crafted input processed by the unserialize() function could cause a PHP application to disclose portion of its memory or crash.

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. A flaw was found in the way PHP parsed multipart HTTP POST requests. A specially crafted request could cause PHP to use an excessive amount of CPU time. An uninitialized pointer use flaw was found in PHP's Exif extension. A specially crafted JPEG or TIFF file could cause a PHP application using the exif_read_data() function to crash or, possibly, execute arbitrary code with the privileges of the user running that PHP application.
