20 Dec 2018 — QEMU can have an infinite loop in hw/rdma/vmw/pvrdma_dev_ring.c because return values are not checked (and -1 is mishandled). QEMU puede tener un bucle infinito en hw/rdma/vmw/pvrdma_dev_ring.c debido a que no se comprueban los valores de retorno (y -1 se gestiona de manera incorrecta). Michael Hanselmann discovered that QEMU incorrectly handled the Media Transfer Protocol. An attacker inside the guest could use this issue to read or write arbitrary files and cause a denial of service, or possibly execute a... • http://www.openwall.com/lists/oss-security/2018/12/19/2 • CWE-252: Unchecked Return Value CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
