Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-32628 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- keydb (Bitnami): affected from 5.0.0; fixed in 5.0.14, 6.0.16, 6.2.6\n- redis (Bitnami): affected from 5.0.0; fixed in 5.0.14, 6.0.16, 6.2.6\n- valkey (Bitnami): affected from 5.0.0; fixed in 5.0.14, 6.0.16, 6.2.6\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2021-32628/ (Markdown: https://insights.sbomify.com/CVE-2021-32628/index.md)","id":"CVE-2021-32628","markdown":"https://insights.sbomify.com/CVE-2021-32628/index.md","name":"CVE-2021-32628","record":{"aliases":["ALPINE-CVE-2021-32628","AZL-6846","BIT-keydb-2021-32628","BIT-redis-2021-32628","BIT-valkey-2021-32628","CLEANSTART-2026-NQ76206","DEBIAN-CVE-2021-32628","GHSA-vw22-qm3h-49pr","UBUNTU-CVE-2021-32628"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Redis in-memory database","requires_auth":"low_privilege","summary":"An integer overflow in Redis ziplist handling allows remote code execution if default configuration limits are increased, requiring an upgrade or ACL restrictions.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"management_services_for_element_software","vendor":"netapp"},{"product":"management_services_for_netapp_hci","vendor":"netapp"},{"product":"communications_operations_monitor","vendor":"oracle"},{"product":"redis","vendor":"redis"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-680","name":"Integer Overflow to Buffer Overflow"},{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"Redis is an open source, in-memory database that persists on disk. An integer overflow bug in the ziplist data structure used by all versions of Redis can be exploited to corrupt the heap and potentially result with remote code execution. The vulnerability involves modifying the default ziplist configuration parameters (hash-max-ziplist-entries, hash-max-ziplist-value, zset-max-ziplist-entries or zset-max-ziplist-value) to a very large value, and then constructing specially crafted commands to create very large ziplists. The problem is fixed in Redis versions 6.2.6, 6.0.16, 5.0.14. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from modifying the above configuration parameters. This can be done using ACL to restrict unprivileged users from using the CONFIG SET command.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Vulnerability in handling large ziplists","id":"CVE-2021-32628","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"debian:debian_linux","products":["debian:debian_linux","fedoraproject:fedora"],"type":"integer_overflow","year":"2021"},"n_packages":3,"n_references":9,"next":{"headline":"Memory access due to code generation flaw in Cranelift module","id":"CVE-2021-32629"},"packages":[{"ecosystem":"Bitnami","fixed":["5.0.14","6.0.16","6.2.6"],"introduced":["5.0.0","6.0.0","6.2.0"],"last_affected":[],"package":"keydb","purl":"pkg:bitnami/keydb","source":"BIT-keydb-2021-32628"},{"ecosystem":"Bitnami","fixed":["5.0.14","6.0.16","6.2.6"],"introduced":["5.0.0","6.0.0","6.2.0"],"last_affected":[],"package":"redis","purl":"pkg:bitnami/redis","source":"BIT-redis-2021-32628"},{"ecosystem":"Bitnami","fixed":["5.0.14","6.0.16","6.2.6"],"introduced":["5.0.0","6.0.0","6.2.0"],"last_affected":[],"package":"valkey","purl":"pkg:bitnami/valkey","source":"BIT-valkey-2021-32628"}],"prev":{"headline":"Integer overflow issue with Streams in Redis","id":"CVE-2021-32627"},"products":["redis"],"published":"2021-10-04","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["redis"]},"summary":"An integer overflow in Redis ziplist handling allows remote code execution if default configuration limits are increased, requiring an upgrade or ACL restrictions.","url":"https://insights.sbomify.com/CVE-2021-32628/"}
