A flaw was found in libvirt. A refactor of the code fetching the list of interfaces for multiple APIs introduced a corner case on platforms where allocating 0 bytes of memory results in a NULL pointer. This corner case would lead to a NULL-pointer dereference and subsequent crash of virtinterfaced. This issue could allow clients connecting to the read-only socket to crash the virtinterfaced daemon.

| Summary | (es) Se encontró un fallo en libvirt. Una refactorización del código que obtiene la lista de interfaces para múltiples API introdujo un caso extremo en plataformas donde la asignación de 0 bytes de memoria da como resultado un puntero NULL. Este caso extremo conduciría a una desreferencia de puntero NULL y al posterior bloqueo de virtinterfaced. Este problema podría permitir que los clientes que se conectan al socket de solo lectura bloqueen el demonio virtinterfaced. | |
