CVE-2016-7412 – php: Heap overflow in mysqlnd when not receiving UNSIGNED_FLAG in BIT field

https://notcve.org/view.php?id=CVE-2016-7412

ext/mysqlnd/mysqlnd_wireprotocol.c in PHP before 5.6.26 and 7.x before 7.0.11 does not verify that a BIT field has the UNSIGNED_FLAG flag, which allows remote MySQL servers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via crafted field metadata. ext/mysqlnd/mysqlnd_wireprotocol.c en PHP en versiones anteriores a 5.6.26 y 7.x en versiones anteriores a 7.0.11 no verifica que un campo BIT tenga el indicador UNSIGNED_FLAG, lo que podría permitir a servidores MySQL remotos provocar una denegación de servicio (desbordamiento de búfer basado en memoria dinámica) o tener otro posible impacto no especificado a través de metadatos de campo manipulado. • http://www.openwall.com/lists/oss-security/2016/09/15/10 http://www.php.net/ChangeLog-5.php http://www.php.net/ChangeLog-7.php http://www.securityfocus.com/bid/93005 http://www.securitytracker.com/id/1036836 https://access.redhat.com/errata/RHSA-2018:1296 https://bugs.php.net/bug.php?id=72293 https://github.com/php/php-src/commit/28f80baf3c53e267c9ce46a2a0fadbb981585132?w=1 https://security.gentoo.org/glsa/201611-22 https://www.tenable.com/security/tns-2016-19 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •

CVE-2016-7417 – php: Missing type check when unserializing SplArray

https://notcve.org/view.php?id=CVE-2016-7417

ext/spl/spl_array.c in PHP before 5.6.26 and 7.x before 7.0.11 proceeds with SplArray unserialization without validating a return value and data type, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted serialized data. ext/spl/spl_array.c en PHP en versiones anteriores a 5.6.26 y 7.x en versiones anteriores a 7.0.11 procede con SplArray no serializado sin validar un valor de retorno y tipo de dato, lo que permite a atacantes remotos provocar una denegación de servicio o tener otro posible impacto no especificado a través de datos serializados manipulados. • http://www.openwall.com/lists/oss-security/2016/09/15/10 http://www.php.net/ChangeLog-5.php http://www.php.net/ChangeLog-7.php http://www.securityfocus.com/bid/93007 http://www.securitytracker.com/id/1036836 https://access.redhat.com/errata/RHSA-2018:1296 https://bugs.php.net/bug.php?id=73029 https://github.com/php/php-src/commit/ecb7f58a069be0dec4a6131b6351a761f808f22e?w=1 https://security.gentoo.org/glsa/201611-22 https://www.tenable.com/security/tns-2016-19 • CWE-20: Improper Input Validation CWE-252: Unchecked Return Value •

CVE-2016-7418 – php: Null pointer dereference in php_wddx_push_element

https://notcve.org/view.php?id=CVE-2016-7418

The php_wddx_push_element function in ext/wddx/wddx.c in PHP before 5.6.26 and 7.x before 7.0.11 allows remote attackers to cause a denial of service (invalid pointer access and out-of-bounds read) or possibly have unspecified other impact via an incorrect boolean element in a wddxPacket XML document, leading to mishandling in a wddx_deserialize call. La función php_wddx_push_element en ext/wddx/wddx.c en PHP en versiones anteriores a 5.6.26 y 7.x en versiones anteriores a 7.0.11 permite a atacantes remotos provocar una denegación de servicio (acceso a puntero no válido y lectura fuera de límites) o tener otro posible impacto no especificado a través de un elemento booleano incorrecto en un documento XML wddxPacket, produciendo una manejo incorrecto en una llamada wddx_deserialize. • http://www.openwall.com/lists/oss-security/2016/09/15/10 http://www.php.net/ChangeLog-5.php http://www.php.net/ChangeLog-7.php http://www.securityfocus.com/bid/93011 http://www.securitytracker.com/id/1036836 https://access.redhat.com/errata/RHSA-2018:1296 https://bugs.php.net/bug.php?id=73065 https://github.com/php/php-src/commit/c4cca4c20e75359c9a13a1f9a36cb7b4e9601d29?w=1 https://security.gentoo.org/glsa/201611-22 https://www.tenable.com/security/tns-2016-19 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-476: NULL Pointer Dereference •

CVE-2016-7413 – php: Use after free in wddx_deserialize

https://notcve.org/view.php?id=CVE-2016-7413

Use-after-free vulnerability in the wddx_stack_destroy function in ext/wddx/wddx.c in PHP before 5.6.26 and 7.x before 7.0.11 allows remote attackers to cause a denial of service or possibly have unspecified other impact via a wddxPacket XML document that lacks an end-tag for a recordset field element, leading to mishandling in a wddx_deserialize call.

ext/standard/var_unserializer.c in PHP before 5.6.25 and 7.x before 7.0.10 mishandles certain invalid objects, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted serialized data that leads to a (1) __destruct call or (2) magic method call. ext/standard/var_unserializer.c en PHP en versiones anteriores a 5.6.25 y 7.x en versiones anteriores a 7.0.10 no maneja adecuadamente ciertos objetos no válidos, lo que permite a atacantes remotos provocar una denegación de servicio o tener otro posible impacto no especificado a través de datos serializados manipulados que conducen a (1) una llamada __destruct o (2) una llamada al método mágico. • http://openwall.com/lists/oss-security/2016/09/02/9 http://rhn.redhat.com/errata/RHSA-2016-2750.html http://www.php.net/ChangeLog-5.php http://www.php.net/ChangeLog-7.php http://www.securityfocus.com/bid/92756 http://www.securitytracker.com/id/1036680 https://bugs.php.net/bug.php?id=72663 https://github.com/php/php-src/commit/20ce2fe8e3c211a42fee05a461a5881be9a8790e?w=1 https://security.gentoo.org/glsa/201611-22 https://www.tenable.com/security/tns-2016-19 http • CWE-502: Deserialization of Untrusted Data •
