Status Candidate

Overview

The make_response function in drivers/block/xen-blkback/blkback.c in the Linux kernel before 4.11.8 allows guest OS users to obtain sensitive information from host OS (or other guest OS) kernel memory by leveraging the copying of uninitialized padding fields in Xen block-interface response structures, aka XSA-216.

Ubuntu Security Notice 3414-2 - USN-3414-1 fixed vulnerabilities in QEMU. The patch backport for CVE-2017-9375 was incomplete and caused a regression in the USB xHCI controller emulation support. This update fixes the problem. Leo Gaspard discovered that QEMU incorrectly handled VirtFS access control. A guest attacker could use this issue to elevate privileges inside the guest. Li Qiang discovered that QEMU incorrectly handled VMWare PVSCSI emulation. A privileged attacker inside the guest could use this issue to cause QEMU to consume resources or crash, resulting in a denial of service. Various other issues were also addressed.
