  "summary": "CVE-2021-32628 is fixed in 6 products on 1 platform, first by redis 5:4.0.9-1ubuntu0.2\u002Besm3, released October 4, 2021. It is not reported as exploited. Patch Radar priority: High.",
  "title": "redis: Redis is an advanced key-value store",
  "description": "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.",
