{"id":"RLSA-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":"2026-02-05T01:45:17.377501Z","published":"2021-10-20T12:46:40Z","upstream":["CVE-2021-32626","CVE-2021-32627","CVE-2021-32628","CVE-2021-32675","CVE-2021-32687","CVE-2021-41099"],"references":[{"type":"ADVISORY","url":"https://errata.rockylinux.org/RLSA-2021:3945"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2010991"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2011000"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2011004"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2011010"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2011017"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2011020"}],"affected":[{"package":{"name":"redis","ecosystem":"Rocky Linux:8","purl":"pkg:rpm/rocky-linux/redis?distro=rocky-linux-8&epoch=0"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0:6.0.9-5.module+el8.5.0+658+72172854"}],"database_specific":{"yum_repository":"AppStream"}}],"database_specific":{"source":"https://storage.googleapis.com/resf-osv-data/RLSA-2021:3945.json"}},{"package":{"name":"redis","ecosystem":"Rocky Linux:8","purl":"pkg:rpm/rocky-linux/redis?distro=rocky-linux-8-4-legacy&epoch=0"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0:6.0.9-5.module+el8.4.0+660+a8447b97"}],"database_specific":{"yum_repository":"AppStream"}}],"database_specific":{"source":"https://storage.googleapis.com/resf-osv-data/RLSA-2021:3945.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"}],"credits":[{"name":"Rocky Enterprise Software Foundation"},{"name":"Red Hat"}]}
