Dist Opensuse Esm H88
An update for openSUSE has been released to resolve a qemu vulnerability that could lead to denial of service, alongside several corrective measures. Get the details!
An update that solves one vulnerability and has four fixes is now available.

Description

This update for qemu fixes the following issues:

This security issue was fixed:

- CVE-2018-12617: qmp_guest_file_read had an integer overflow that could

have been exploited by sending a crafted QMP command (including

guest-file-read with a large count value) to the agent via the listening

socket causing DoS (bsc#1098735)

These non-security issues were fixed:

- Allow kvm group access to /dev/sev (bsc#1102604).

- Fix for the value used for reduced_phys_bits. Please update the

reduced_phys_bits value used on the commandline or in libvirt XML to the

value 1 (explicitly set now in QEMU code). (bsc#1103628)

- Fix (again) the qemu guest agent udev rule file, which got unfixed in a

series of unfortunate events (bsc#1094898 and now bsc#1105279)

This update was imported from the SUSE:SLE-15:Update update project.
