Descriptions

ext/intl/msgformat/msgformat_format.c in PHP before 5.6.26 and 7.x before 7.0.11 does not properly restrict the locale length provided to the Locale class in the ICU library, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a MessageFormatter::formatMessage call with a long first argument.

ext/intl/msgformat/msgformat_format.c en PHP en versiones anteriores a 5.6.26 y 7.x en versiones anteriores a 7.0.11 no restringe adecuadamente la longitud proporcionada a locale para la clase Locale en la libreria ICU, lo que permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) o tener otro posible impacto no especificado a través de una llamada MessageFormatter::formatMessage con un primer argumento grande.

Taoguang Chen discovered that PHP incorrectly handled certain invalid objects when unserializing data. A remote attacker could use this issue to cause PHP to crash, resulting in a denial of service, or possibly execute arbitrary code. Taoguang Chen discovered that PHP incorrectly handled invalid session names. A remote attacker could use this issue to inject arbitrary session data. Various other issues were also addressed.
