Summary
Felipe Franciosi, Raphael Norwitz, and Peter Turschmid discovered that QEMU
incorrectly handled iSCSI server responses. A remote attacker in control of
the iSCSI server could use this issue to cause QEMU to crash, leading to a
denial of service, or possibly execute arbitrary code. (CVE-2020-1711)
It was discovered that the QEMU libslirp component incorrectly handled
