"This update for qemu fixes the following issues :

These security issues were 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).

  - CVE-2018-11806: Prevent heap-based buffer overflow via
    incoming fragmented datagrams (bsc#1096223).

With this release the mitigations for Spectre v4 are moved the the
patches from upstream (CVE-2018-3639, bsc#1092885).

This feature was added :

  - Add support for block resize support for disks through
    the monitor (bsc#1094725).

This update was imported from the SUSE:SLE-12-SP3:Update update
project."
