There is a remote code execution vulnerability in MoinMoin wiki,
versions 1.9.x up to (and including) 1.9.5. The method save in class
AnyWikiDraw (action/anywikidraw.py) and class TWikiDraw
(action/twikidraw.py) do not filter user supplied input correctly, which
leads to a path traversal vulnerability, which can be exploited to
execute arbitrary code with moin's privileges. An exploit was seen in the wild.
