CVE-2016-10158 – php: Wrong calculation in exif_convert_any_to_int function
https://notcve.org/view.php?id=CVE-2016-10158
The exif_convert_any_to_int function in ext/exif/exif.c in PHP before 5.6.30, 7.0.x before 7.0.15, and 7.1.x before 7.1.1 allows remote attackers to cause a denial of service (application crash) via crafted EXIF data that triggers an attempt to divide the minimum representable negative integer by -1. La función exif_convert_any_to_int en ext/exif/exif.c en PHP en versiones anteriores a 5.6.30, 7.0.x en versiones anteriores a 7.0.15, y 7.1.x en versiones anteriores a 7.1.1 permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) a través de datos EXIF manipulados que desencadenan un intento de dividir el entero negativo mínimo representable por -1. It was found that the exif_convert_any_to_int() function in PHP was vulnerable to floating point exceptions when parsing tags in image files. A remote attacker with the ability to upload a malicious image could crash PHP, causing a Denial of Service. • http://php.net/ChangeLog-5.php http://php.net/ChangeLog-7.php http://www.debian.org/security/2017/dsa-3783 http://www.securityfocus.com/bid/95764 http://www.securitytracker.com/id/1037659 https://access.redhat.com/errata/RHSA-2018:1296 https://bugs.php.net/bug.php?id=73737 https://github.com/php/php-src/commit/1cda0d7c2ffb62d8331c64e703131d9cabdc03ea https://security.gentoo.org/glsa/201702-29 https://security.netapp.com/advisory/ntap-20180112-0001 https://www.tenable.co • CWE-189: Numeric Errors CWE-682: Incorrect Calculation •

Integer overflow in the phar_parse_pharfile function in ext/phar/phar.c in PHP before 5.6.30 and 7.0.x before 7.0.15 allows remote attackers to cause a denial of service (memory consumption or application crash) via a truncated manifest entry in a PHAR archive. Desbordamiento de entero en la función phar_parse_pharfile en ext/phar/phar.c en PHP en versiones anteriores a 5.6.30 y 7.0.x en versiones anteriores a 7.0.15 permite a atacantes remotos provocar una denegación de servicio (consumo de memoria o caída de aplicación) a través de una entrada de manifiesto truncado en un archivo PHAR. • http://php.net/ChangeLog-5.php http://php.net/ChangeLog-7.php http://www.debian.org/security/2017/dsa-3783 http://www.securityfocus.com/bid/95774 http://www.securitytracker.com/id/1037659 https://access.redhat.com/errata/RHSA-2018:1296 https://bugs.php.net/bug.php?id=73764 https://github.com/php/php-src/commit/ca46d0acbce55019b970fcd4c1e8a10edfdded93 https://security.gentoo.org/glsa/201702-29 https://security.netapp.com/advisory/ntap-20180112-0001 https://www.tenable.co • CWE-190: Integer Overflow or Wraparound •
CVE-2016-10161 – php: Out-of-bounds heap read on unserialize in finish_nested_data()

The object_common1 function in ext/standard/var_unserializer.c in PHP before 5.6.30, 7.0.x before 7.0.15, and 7.1.x before 7.1.1 allows remote attackers to cause a denial of service (buffer over-read and application crash) via crafted serialized data that is mishandled in a finish_nested_data call. La función object_common1 en ext/standard/var_unserializer.c en PHP en versiones anteriores a 5.6.30, 7.0.x en versiones anteriores a 7.0.15 y 7.1.x en versiones anteriores a 7.1.1 permite a atacantes remotos provocar una denegación de servicio (sobre lectura de búfer y caída de aplicación) a través de datos serializados manipulados que se maneja mal en una llamada finish_nested_data. • http://php.net/ChangeLog-5.php http://php.net/ChangeLog-7.php http://www.debian.org/security/2017/dsa-3783 http://www.securityfocus.com/bid/95768 http://www.securitytracker.com/id/1037659 https://access.redhat.com/errata/RHSA-2018:1296 https://bugs.php.net/bug.php?id=73825 https://github.com/php/php-src/commit/16b3003ffc6393e250f069aa28a78dc5a2c064b2 https://security.gentoo.org/glsa/201702-29 https://security.netapp.com/advisory/ntap-20180112-0001 https://www.tenable.co • CWE-125: Out-of-bounds Read •
CVE-2016-10162 – php: Null pointer dereference when unserializing PHP object

The php_wddx_pop_element function in ext/wddx/wddx.c in PHP 7.0.x before 7.0.15 and 7.1.x before 7.1.1 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an inapplicable class name in a wddxPacket XML document, leading to mishandling in a wddx_deserialize call. La función php_wddx_pop_element en ext/wddx/wddx.c en PHP 7.0.x en versiones anteriores a 7.0.15 y 7.1.x en versiones anteriores a 7.1.1 permite a atacantes remotos provocar una denegación de servicio (referencia a puntero NULL y caída de aplicación) a través de un nombre de clase inaplicable en un documento XML wddxPacket, esto lleva a un mal manejo en una llamada la wddx_deserialize. • http://php.net/ChangeLog-7.php http://www.securityfocus.com/bid/95668 http://www.securitytracker.com/id/1037659 https://access.redhat.com/errata/RHSA-2018:1296 https://bugs.php.net/bug.php?id=73831 https://github.com/php/php-src/commit/8d2539fa0faf3f63e1d1e7635347c5b9e777d47b https://access.redhat.com/security/cve/CVE-2016-10162 https://bugzilla.redhat.com/show_bug.cgi?id=1419012 • CWE-476: NULL Pointer Dereference •
CVE-2016-7479 – php: Use-after-free vulnerability when resizing the 'properties' hash table of a serialized object
https://notcve.org/view.php?id=CVE-2016-7479
In all versions of PHP 7, during the unserialization process, resizing the 'properties' hash table of a serialized object may lead to use-after-free. A remote attacker may exploit this bug to gain arbitrary code execution. En todas las versiones de PHP 7, durante el proceso no serializado, redimensionando las "propiedades" de la tabla hash de un objeto serializado puede conducir a un uso después de liberación de memoria. Un atacante remoto puede explotar este error para obtener ejecución de código arbitraria. • http://blog.checkpoint.com/2016/12/27/check-point-discovers-three-zero-day-vulnerabilities-web-programming-language-php-7 http://blog.checkpoint.com/wp-content/uploads/2016/12/PHP_Technical_Report.pdf http://www.securityfocus.com/bid/95151 http://www.securitytracker.com/id/1037659 https://access.redhat.com/errata/RHSA-2018:1296 https://bugs.php.net/bug.php?id=73092 https://security.netapp.com/advisory/ntap-20180112-0001 https://www.youtube.com/watch?v=LDcaPstAuPk https://access. • CWE-416: Use After Free •
