RHEL 7 : qemu-kvm (RHSA-2017:2445)

high Nessus Plugin ID 102306

Synopsis

The remote Red Hat host is missing a security update for qemu-kvm.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2017:2445 advisory.

Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm package provides the user-space component for running virtual machines that use KVM.

Security Fix(es):

* Quick Emulator (QEMU) built with the Network Block Device (NBD) Server support is vulnerable to a crash via a SIGPIPE signal. The crash can occur if a client aborts a connection due to any failure during negotiation or read operation. A remote user/process could use this flaw to crash the qemu-nbd server resulting in a DoS. (CVE-2017-10664)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL qemu-kvm package based on the guidance in RHSA-2017:2445.
