BIT-brotli-2020-8927 — Buffer overflow in Brotli library

Affected: Bitnami: brotli

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. It is recommended to update your Brotli library to 1.0.8 or later. If one cannot update, we recommend to use the "streaming" API as opposed to the "one-shot" API, and impose chunk size limits.

CVE-2020-36846 — IO::Compress::Brotli versions prior to 0.007 for Perl have an integer overflow in the bundled Brotli C library

Affected: TIMLEGGE IO::Compress::Brotli

A buffer overflow, as described in CVE-2020-8927, exists in the embedded Brotli library. Versions of IO::Compress::Brotli prior to 0.007 included a version of the brotli library prior to version 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. It is recommended to update your IO::Compress::Brotli module to 0.007 or later. If one cannot update, we recommend to use the "streaming" API as opposed to the "one-shot" API, and impose chunk size limits.

Affected: PyPI: brotli

RUSTSEC-2021-0131 — Integer overflow in the bundled Brotli C library

Affected: crates.io: brotli-sys

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.
