No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Integer overflow in the isofs_real_read_zf function in isofs.c in FuseISO 20070708 might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a large ZF block size in an ISO file, leading to a heap-based buffer overflow.
