Description

This update for samba fixes the following issues :

CVE-2020-10745: Fixed an issue which parsing and packing of NBT and DNS packets containing dots could potentially have consumed excessive CPU (bsc#1173160).

CVE-2020-14303: Fixed an endless loop when receiving at AD DC empty UDP packets (bsc#1173359).

Added libnetapi-devel to baselibs conf, for wine usage (bsc#1172307).

Fixed an installing issue where samba - samba-ad-dc.service did not exist and unit was not found (bsc#1171437).

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.
