Not sure which component this should go under so I copied bug 366559 for now.

I am fuzzing commit https://github.com/google/brotli/commit/ca29aa22c295daac15baf5d85427ecc7808b515c

This is the version of brotli currently shipping in Firefox (https://hg.mozilla.org/mozilla-central/log/tip/modules/brotli/dec/decode.c).

It is currently used in WOFF2.

per https://bugzilla.mozilla.org/show_bug.cgi?id=1207298#c12 we are going to let the brotli library update ride the trains from 44 onwards unless we learn of more severe problems..

bug 1207298 checked in a library update and will also resolve this issue.
