This update for qemu fixes the following issues :
Security issue fixed :
CVE-2020-1983: Fixed a use-after-free in the ip_reass function of slirp (bsc#1170940).
Non-security issue fixed :
Fixed an issue where limiting the memory bandwidth was not possible (bsc#1167816).
Miscellaneous fixes to the in-package support documentation.
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.
