CVE-2016-7412

Estado: ModificadaAlta (8.1)—

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.

CVSS

Versión: 3.0
Vector: CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
