CVE-2020-36846

IO::Compress::Brotli versions prior to 0.007 for Perl have an integer overflow in the bundled Brotli C library

Published: May 30, 2025Updated: May 30, 2025 Sources: CVE List NVD

Description

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.
