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.
