Fedora 25 : python-wikitcms (2016-fce8b939c9)

Description

This update contains a SECURITY fix for an issue with potentially serious consequences but very limited scope. If an administrator of a wiki you talked to using python-wikitcms were malicious, they could cause arbitrary code execution as the user running wikitcms. No-one besides a wiki administrator could do this, as it requires crafting the wiki's response to an edit request to include a malicious payload.

It also drops some now useless or unneeded code (due to changes in mediawiki and mwclient).

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
