The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:3369 advisory.
KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm-rhev packages provide the user-space component for running virtual machines that use KVM in environments managed by Red Hat products.
Security Fix(es):
* Quick Emulator (QEMU), compiled with qemu_map_ram_ptr to access guests' RAM block area, is vulnerable to an OOB r/w access issue. The crash can occur if a privileged user inside a guest conducts certain DMA operations, resulting in a DoS. (CVE-2017-11334)
* Quick Emulator (QEMU), compiled with the PC System Emulator with multiboot feature support, is vulnerable to an OOB r/w memory access issue. The issue could occur due to an integer overflow while loading a kernel image during a guest boot. A user or process could use this flaw to potentially achieve arbitrary code execution on a host. (CVE-2017-14167)
* Quick emulator (QEMU), compiled with the Cirrus CLGD 54xx VGA Emulator support, is vulnerable to an OOB write access issue. The issue could occur while writing to VGA memory via mode4and5 write functions. A privileged user inside guest could use this flaw to crash the QEMU process resulting in Denial of Serivce (DoS). (CVE-2017-15289)
Red Hat would like to thank Alex for reporting CVE-2017-11334; Thomas Garnier (Google.com) for reporting CVE-2017-14167; and Guoxiang Niu (Huawei.com) for reporting CVE-2017-15289.
Bug Fix(es):
* Improvements made for qemu 2.9 to the NBD code used during live storage migration were not robust to an abrupt exit of the other end of the connection; the result was that live migration could fail if the source side NBD connection failed. The NBD code has been fixed to be more robust regardless of what the other side of the connection does. (BZ#1495474)
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
