Multiple use-after-free vulnerabilities in SPL in PHP before 5.4.44, 5.5.x before 5.5.28, and 5.6.x before 5.6.12 allow remote attackers to execute arbitrary code via vectors involving (1) ArrayObject, (2) SplObjectStorage, and (3) SplDoublyLinkedList, which are mishandled during unserialization. Múltiples vulnerabilidades de uso después de liberación de memoria en SPL en PHP en versiones anteriores a 5.4.44, 5.5.x en versiones anteriores a 5.5.28 y 5.6.x en versiones anteriores a 5.6.12 permiten a atacantes remotos ejecutar código arbitrario involucrando vectores (1) ArrayObject, (2) SplObjectStorage y (3) SplDoublyLinkedList, los cuales no son manejados adecuadamente durante la deserialización. 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-3344 http://www.openwall.com/lists/oss-security/2015/08/19/3 http://www.php.net/ChangeLog-5.php http://www.securityfocus.com/bid/76737 https://bugs.php.net/bug.php?id=70155 https://bugs.php.net/bug.php?id=70166 https://bugs.php.net/bug.php?id=70168 https://bugs.php.net/bug.php?id=70169 https://security.gentoo.org/glsa/201606-10 https://access.redhat.com/security/cve/CVE-2015-6831 https://bugzilla.r • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2015-6837
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 during initial error checking, 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-2015-6838. 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 durante la comprobación inicial de errores, lo que permite a atacantes remotos provocar una denegación de servicio (referencia a puntero NULO 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/76738 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-2015-6837 https://bugzilla.redhat.com/show_bug.cgi?id=1260711 • CWE-476: NULL Pointer Dereference •
