Descriptions

Qemu before 1.6.2 block diver for the various disk image formats used by Bochs and for the QCOW version 2 format, are vulnerable to a possible crash caused by signed data types or a logic error while creating QCOW2 snapshots, which leads to incorrectly calling update_refcount() routine.

Qemu versiones anteriores a 1.6.2 del buceador de bloques para los distintos formatos de imagen de disco usados por Bochs y para el formato QCOW versión 2, son vulnerables a un posible bloqueo causado por los tipos de datos firmados o por un error lógico mientras son creadas las instantáneas de QCOW2, que conlleva a una llamada incorrecta a la rutina update_refcount()
