qemu is vulnerable to Out-of-bounds Read. An out-of-bounds read flaw was found qxl_phys2virt() function which does not check the size of the structure pointed to by the guest physical address, potentially reading past the end of the bar space into adjacent pages. A malicious guest user could use this flaw to crash the QEMU process on the host causing a denial of service condition.
