ALSA-2021:1702
Vulnerability from osv_almalinux – Published: 2021-05-18 05:52 – Updated: 2021-11-12 10:20 – Source websiteBrotli 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)
