Integer overflow in the bundled Brotli C library
A buffer overflow exists in the Brotli library versions prior to 1.0.8 where an attacker controlling the input length of a "one-shot" decompression request to a script can trigger a crash, which happens when copying over chunks of data larger than 2 GiB. If one cannot update the C library, its authors recommend to use the "streaming" API as opposed to the "one-shot" API, and impose chunk size limits.
