Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-41099 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-2021-41099/ (Markdown: https://insights.sbomify.com/CVE-2021-41099/index.md)","id":"CVE-2021-41099","markdown":"https://insights.sbomify.com/CVE-2021-41099/index.md","name":"CVE-2021-41099","record":{"aliases":["ALPINE-CVE-2021-41099","AZL-6853","BIT-keydb-2021-41099","BIT-redis-2021-41099","BIT-valkey-2021-41099","CLEANSTART-2026-HA19484","DEBIAN-CVE-2021-41099","GHSA-j3cr-9h5g-6cph","UBUNTU-CVE-2021-41099"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Redis in-memory database","requires_auth":"low_privilege","summary":"An integer overflow in Redis allows heap corruption and potential remote code execution if the proto-max-bulk-len parameter is set to a large value.","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_and_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 underlying string library can be used to corrupt the heap and potentially result with denial of service or remote code execution. The vulnerability involves changing the default proto-max-bulk-len configuration parameter to a very large value and constructing specially crafted network payloads or commands. The problem is fixed in Redis versions 6.2.6, 6.0.16 and 5.0.14. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from modifying the proto-max-bulk-len configuration parameter. 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":"Integer overflow issue with strings in Redis","id":"CVE-2021-41099","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":"Account takeover when having only access to a user's short lived token in wire-server","id":"CVE-2021-41100"},"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-2021-41099"},{"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-2021-41099"},{"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-2021-41099"}],"prev":{"headline":"Improper Restriction of XML External Entity Reference (XXE) in Nokogiri on JRuby","id":"CVE-2021-41098"},"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":"2024-08-04","vendors":["redis"]},"summary":"An integer overflow in Redis allows heap corruption and potential remote code execution if the proto-max-bulk-len parameter is set to a large value.","url":"https://insights.sbomify.com/CVE-2021-41099/"}
