Fedora 27 : 2:qemu (2017-8db9c497f9)

Medium Nessus Plugin ID 105928

Synopsis

The remote Fedora host is missing a security update.

Description

- Fix ppc64 KVM failure (bz #1501936)

- CVE-2017-15038: 9p: information disclosure when reading extended attributes (bz #1499111)

- CVE-2017-15268: potential memory exhaustion via websock connection to VNC (bz #1496882)

----

qemu-pr-helper didn't work due to a change in the libmultipath/libmpathpersist APIs exposed by device-mapper-multipath-devel. This has been fixed now. Other small changes to the qemu-pr-helper service are included.

----

Backport qemu-pr-helper from QEMU 2.11. This daemon allows unprivileged users (who have access to the daemon) to use persistent reservation commands on both regular disks and multipath block devices.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected 2:qemu package.
