CVSS: 7.5EPSS: 2%CPEs: 60EXPL: 0CVE-2015-6836 – php: SOAP serialize_function_call() type confusion
https://notcve.org/view.php?id=CVE-2015-6836
The SoapClient __call method in ext/soap/soap.c in PHP before 5.4.45, 5.5.x before 5.5.29, and 5.6.x before 5.6.13 does not properly manage headers, which allows remote attackers to execute arbitrary code via crafted serialized data that triggers a "type confusion" in the serialize_function_call function. El método SoapClient __call en ext/soap/soap.c en PHP en versiones anteriores a 5.4.45, 5.5.x en versiones anteriores a 5.5.29 y 5.6.x en versiones anteriores a 5.6.13 no maneja adecuadamente las cabeceras, lo que permite a atacantes remotos ejecutar código arbitrario a través de datos serializados manipulados que desencadenan un "type confusion" en la función serialize_function_call. 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. • http://www.debian.org/security/2015/dsa-3358 http://www.php.net/ChangeLog-5.php http://www.securityfocus.com/bid/76644 http://www.securitytracker.com/id/1033548 https://bugs.php.net/bug.php?id=70388 https://security.gentoo.org/glsa/201606-10 https://access.redhat.com/security/cve/CVE-2015-6836 https://bugzilla.redhat.com/show_bug.cgi?id=1260683 • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •
CVSS: 7.5EPSS: 2%CPEs: 66EXPL: 0CVE-2015-6838 – php: NULL pointer dereference in XSLTProcessor class
https://notcve.org/view.php?id=CVE-2015-6838
The xsl_ext_function_php function in ext/xsl/xsltprocessor.c in PHP before 5.4.45, 5.5.x before 5.5.29, and 5.6.x before 5.6.13, when libxml2 before 2.9.2 is used, does not consider the possibility of a NULL valuePop return value before proceeding with a free operation after the principal argument loop, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted XML document, a different vulnerability than CVE-2015-6837. La función xsl_function_php en ext/xsl/xsl/xsltprocessor.c en PHP en versiones anteriores a 5.4.45, 5.5.x en versiones anteriores a 5.5.29 y 5.6.x en versiones anteriores a 5.6.13, cuando se utiliza libxml2 en versiones anteriores a 2.9.2, no considera la posibilidad de un retorno NULL valuePop antes de proceder a una operación libre despues del bucle del argumento principal, lo que permite a atacantes remotos provocar una denegación de servicio (referencia a puntero NULL y caída de aplicación) a través de un documento XML manipulado, una vulnerabilidad diferente a CVE-2015-6838. 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. • http://php.net/ChangeLog-5.php http://www.debian.org/security/2015/dsa-3358 http://www.securityfocus.com/bid/76733 http://www.securitytracker.com/id/1033548 https://bugs.php.net/bug.php?id=69782 https://security.gentoo.org/glsa/201606-10 https://access.redhat.com/security/cve/CVE-2015-6838 https://bugzilla.redhat.com/show_bug.cgi?id=1260711 • CWE-476: NULL Pointer Dereference •

The session deserializer in PHP before 5.4.45, 5.5.x before 5.5.29, and 5.6.x before 5.6.13 mishandles multiple php_var_unserialize calls, which allow remote attackers to execute arbitrary code or cause a denial of service (use-after-free) via crafted session content. La sesión deserializer en PHP en versiones anteriores a 5.4.45, 5.5.x en versiones anteriores a 5.5.29 y 5.6.x en versiones anteriores a 5.6.13 no es correctamente manejada en llamadas multiples php_var_unserialize, lo que permite a atacantes remotos ejecutar código arbitrario o causar una denegación del servicio (uso después de liberación de memoria) a través de una sesión de contenido manipulada. 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. • https://www.exploit-db.com/exploits/38123 https://github.com/ockeghem/CVE-2015-6835-checker http://php.net/ChangeLog-5.php http://www.debian.org/security/2015/dsa-3358 http://www.securityfocus.com/bid/76734 http://www.securitytracker.com/id/1033548 https://bugs.php.net/bug.php?id=70219 https://security.gentoo.org/glsa/201606-10 https://access.redhat.com/security/cve/CVE-2015-6835 https://bugzilla.redhat.com/show_bug.cgi?id=1260647 • CWE-416: Use After Free •

The phar_convert_to_other function in ext/phar/phar_object.c in PHP before 5.4.43, 5.5.x before 5.5.27, and 5.6.x before 5.6.11 does not validate a file pointer before a close operation, which allows remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other impact via a crafted TAR archive that is mishandled in a Phar::convertToData call. La función phar_convert_to_other en ext/phar_objetc.c en PHP en versiones anteriores a 5.4.43, 5.5.x en versiones anteriores a 5.5.27 y 5.6.x en versiones anteriores a 5.6.11 no valida un apuntador de archivo antes de una operación de cierre, lo que permite a atacantes remotos provocar una denegación de servicio (fallo de segmentación) o tener un posible impacto no especificado a través de un archivo TAR manipulado que no es correctamente manejado en una llamada Phar::convertToData.
