Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for xen fixes the following issues :

CVE-2019-15890: Fixed a use-after-free in SLiRP networking implementation of QEMU emulator which could have led to Denial of Service (bsc#1149813).

CVE-2019-12068: Fixed an issue in lsi which could lead to an infinite loop and denial of service (bsc#1146874).

CVE-2019-14378: Fixed a heap buffer overflow in SLiRp networking implementation of QEMU emulator which could have led to execution of arbitrary code with privileges of the QEMU process (bsc#1143797).
