Please provide more information about the threat model. Do you mean
that a single PhantomJS process is commonly used to access a series of
independently operated web sites, and the operator of any one web site
could disrupt this use case by placing the crafted SVG file on their
site? Or, do you mean that the only known impact is that one web-site
operator could prevent PhantomJS access (e.g., screenshotting) of
their own web site by using the crafted SVG file -- in other words,
the crash would not realistically disrupt any use of PhantomJS by the
same client to access other web sites?
Is ongoing use of PhantomJS disrupted only in the
http://phantomjs.org/api/webserver/ case? In other words, any one
web-site operator could crash the web server within PhantomJS, and
there would be an outage until the web server within PhantomJS is
manually restarted?
