It is similar in speed with deflate but offers more dense compression. Security Fix(es): * brotli: buffer overflow when input chunk is larger than 2GiB (CVE-2020-8927) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
