RedHat: RHSA-2021-1702:01 Moderate: brotli security update
Summary
Brotli is a generic-purpose lossless compression algorithm that compresses
data using a combination of a modern variant of the LZ77 algorithm, Huffman
coding and 2nd order context modeling, with a compression ratio comparable
to the best currently available general-purpose compression methods. 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)
