Integer overflow in the bundled Brotli C library

Details
Package brotli-sys
Version 0.3.2
URL bitemyapp/brotli2-rs#45
Date 2021-12-20

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.

See advisory page for additional details.
