Security issue fixed :

CVE-2018-15173: Fixed a remote denial of service attack via a crafted
TCP-based service (bsc#1104139).

Non-security issue fixed: Add missing runtime dependency python-xml
which prevented zenmap from starting (bsc#1133512).

has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
