iscsi_aio_ioctl_cb in block/iscsi.c in QEMU 4.1.0 has a heap-based buffer over-read that may disclose unrelated information from process memory to an attacker. A heap buffer overflow flaw was found in the iSCSI support of QEMU. This flaw could lead to an out-of-bounds read access and possible information disclosure from the QEMU process memory to a malicious guest. The highest threat from this vulnerability is to data confidentiality.
