{"id":"ALSA-2021:1702","summary":"Moderate: brotli security update","details":"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. \n\nSecurity Fix(es):\n\n* brotli: buffer overflow when input chunk is larger than 2GiB (CVE-2020-8927)\n\nFor 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.\n\nAdditional Changes:\n\nFor detailed information on changes in this release, see the AlmaLinux Release Notes linked from the References section.","modified":"2026-01-30T01:25:43.800845Z","published":"2021-05-18T05:52:13Z","related":["CVE-2020-8927"],"references":[{"type":"ADVISORY","url":"https://errata.almalinux.org/8/ALSA-2021-1702.html"},{"type":"REPORT","url":"https://vulners.com/cve/CVE-2020-8927"}],"affected":[{"package":{"name":"brotli","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/brotli"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.6-3.el8"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2021:1702.json"}},{"package":{"name":"brotli-devel","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/brotli-devel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.6-3.el8"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2021:1702.json"}},{"package":{"name":"python3-brotli","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/python3-brotli"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.6-3.el8"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2021:1702.json"}}],"schema_version":"1.7.3"}
