Descriptions

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.
