Details

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. An updated version of `brotli-sys` has not been released. 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. In Rust the issue can be mitigated by migrating to the `brotli` crate, which provides a Rust implementation of Brotli compression and decompression that is not affected by this issue.
