This update for qemu fixes the following issues :
Security issues fixed :
CVE-2019-6778: Fixed a heap buffer overflow issue in the SLiRP networking implementation (bsc#1123156).
CVE-2018-16872: Fixed a host security vulnerability related to handling symlinks in usb-mtp (bsc#1119493).
CVE-2018-19489: Fixed a denial of service vulnerability in virtfs (bsc#1117275).
CVE-2018-19364: Fixed a use-after-free if the virtfs interface resulting in a denial of service (bsc#1116717).
CVE-2018-18954: Fixed a denial of service vulnerability related to PowerPC PowerNV memory operations (bsc#1114957).
Non-security issues fixed: Improved disk performance for qemu on xen (bsc#1100408).
Fixed xen offline migration (bsc#1079730, bsc#1101982, bsc#1063993).
Fixed pwrite64/pread64/write to return 0 over -1 for a zero length NULL buffer in qemu (bsc#1121600).
Use /bin/bash to echo value into sys fs for ksm control (bsc#1112646).
Return specification exception for unimplemented diag 308 subcodes rather than a hardware error (bsc#1123179).
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
