This issue was recently minimized and isolated to the circular use of
xlink:hrefs:

https://bugzilla.mozilla.org/show_bug.cgi?id=1297206#c5

Is a CVE suitable for this DoS?

Hello,

Some months ago, we found that just loading this image:

https://dcc.fceia.unr.edu.ar/~ggrieco/oom.svg (518K)

will cause Firefox to consume all your memory. Once you click, you
cannot stop the memory constant memory leak. It can take a few minutes
(we tested in a desktop computer with 16GB). At the end, Firefox will
abort or it will be terminated by the OS.

At least Firefox 49 and 51 in several platforms are affected. A report
in the Mozilla bug tracker was filled:

https://bugzilla.mozilla.org/show_bug.cgi?id=1297206

Please assign a CVE if suitable.

Regards,
Gustavo.
