openSUSE Security Update : qemu (openSUSE-2018-996)

high Nessus Plugin ID 117475

Language:

Synopsis

The remote openSUSE host is missing a security update.

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.

Solution

Update the affected qemu packages.
