CVE-2018-14647: Python's elementtree C accelerator failed to
initialise Expat's hash salt during initialization. This could make it
easy to conduct denial of service attacks against Expat by
constructing an XML document that would cause pathological hash
collisions in Expat's internal data structures, consuming large
amounts CPU and RAM (bsc#1109847)

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."
