Description David Binderman 2015-07-02 16:37:11 UTC 
usr.sbin/bhyve/pci_virtio_block.c:320]: (error) Buffer is accessed out of bounds: sc.vbsc_ident

    sprintf(sc->vbsc_ident, "BHYVE-%02X%02X-%02X%02X-%02X%02X",
        digest[0], digest[1], digest[2], digest[3], digest[4], digest[5]);

sprintf writes 21 bytes into a 20 byte field.
