{"id":"ALSA-2021:3945","summary":"Important: redis:6 security update","details":"Redis is an advanced key-value store. It is often referred to as a data-structure server since keys can contain strings, hashes, lists, sets, and sorted sets. For performance, Redis works with an in-memory data set. You can persist it either by dumping the data set to disk every once in a while, or by appending each command to a log.\n\nSecurity Fix(es):\n\n* redis: Lua scripts can overflow the heap-based Lua stack (CVE-2021-32626)\n\n* redis: Integer overflow issue with Streams (CVE-2021-32627)\n\n* redis: Integer overflow bug in the ziplist data structure (CVE-2021-32628)\n\n* redis: Denial of service via Redis Standard Protocol (RESP) request (CVE-2021-32675)\n\n* redis: Integer overflow issue with intsets (CVE-2021-32687)\n\n* redis: Integer overflow issue with strings (CVE-2021-41099)\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.","modified":"2026-01-30T01:00:59.694141Z","published":"2021-10-20T12:46:40Z","related":["CVE-2021-32626","CVE-2021-32627","CVE-2021-32628","CVE-2021-32675","CVE-2021-32687","CVE-2021-41099"],"references":[{"type":"ADVISORY","url":"https://errata.almalinux.org/8/ALSA-2021-3945.html"},{"type":"REPORT","url":"https://vulners.com/cve/CVE-2021-32626"},{"type":"REPORT","url":"https://vulners.com/cve/CVE-2021-32627"},{"type":"REPORT","url":"https://vulners.com/cve/CVE-2021-32628"},{"type":"REPORT","url":"https://vulners.com/cve/CVE-2021-32675"},{"type":"REPORT","url":"https://vulners.com/cve/CVE-2021-32687"},{"type":"REPORT","url":"https://vulners.com/cve/CVE-2021-41099"}],"affected":[{"package":{"name":"redis","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/redis"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.9-5.module_el8.5.0+67+a3c431d9"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2021:3945.json"}},{"package":{"name":"redis","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/redis"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.9-5.module_el8.4.0+2584+1bb0d2aa"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2021:3945.json"}},{"package":{"name":"redis-devel","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/redis-devel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.9-5.module_el8.5.0+67+a3c431d9"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2021:3945.json"}},{"package":{"name":"redis-devel","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/redis-devel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.9-5.module_el8.4.0+2584+1bb0d2aa"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2021:3945.json"}},{"package":{"name":"redis-doc","ecosystem":"AlmaLinux:8","purl":"pkg:rpm/almalinux/redis-doc"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.9-5.module_el8.4.0+2584+1bb0d2aa"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux8/ALSA-2021:3945.json"}}],"schema_version":"1.7.3"}
