Descriptions

The (1) SSH_MSG_NEWKEYS and (2) SSH_MSG_KEXDH_REPLY packet handlers in package_cb.c in libssh before 0.6.5 do not properly validate state, which allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted SSH packet.

Los manejadores de paquete (1) SSH_MSG_NEWKEYS y (2) SSH_MSG_KEXDH_REPLY en package_cb.c en libssh en versiones anteriores a 0.6.5 no valida correctamente el estado, lo que permite a atacantes remotos provocar una denegación de servicio (referencia a puntero NULL y caída) a través de un paquete SSH manipulado.
