Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-29477 in the wild and no public exploit code.\n\nAffected product: Fedoraproject Fedora. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2021-29477/ (Markdown: https://insights.sbomify.com/CVE-2021-29477/index.md)","id":"CVE-2021-29477","markdown":"https://insights.sbomify.com/CVE-2021-29477/index.md","name":"CVE-2021-29477","record":{"aliases":["ALPINE-CVE-2021-29477","DEBIAN-CVE-2021-29477","GHSA-vqxj-26vj-996g","OESA-2022-1883","RHSA-2021:2034","RLSA-2021:2034"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Redis in-memory store","requires_auth":"low_privilege","summary":"An integer overflow in Redis STRALGO LCS command allows heap corruption and potential remote code execution.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"redis","vendor":"redislabs"}],"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-190","name":"Integer Overflow or Wraparound"}],"description":"Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker.

The problem is fixed in version 6.2.3 and 6.0.13. An additional workaround to mitigate the problem without patching the redis-server executable is to use ACL configuration to prevent clients from using the `STRALGO LCS` command.","ecosystems":["Red Hat:enterprise_linux:8::appstream","Rocky Linux:8"],"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 the STRALGO LCS command","id":"CVE-2021-29477","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"fedoraproject:fedora","products":["fedoraproject:fedora"],"type":"integer_overflow","year":"2021"},"n_packages":6,"n_references":7,"next":{"headline":"Vulnerability in the COPY command for large intsets","id":"CVE-2021-29478"},"packages":[{"ecosystem":"Red Hat:enterprise_linux:8::appstream","fixed":["0:6.0.9-3.module+el8.4.0+10984+ed187465"],"introduced":["0"],"last_affected":[],"package":"redis","purl":"pkg:rpm/redhat/redis","source":"RHSA-2021:2034"},{"ecosystem":"Red Hat:enterprise_linux:8::appstream","fixed":["0:6.0.9-3.module+el8.4.0+10984+ed187465"],"introduced":["0"],"last_affected":[],"package":"redis-debuginfo","purl":"pkg:rpm/redhat/redis-debuginfo","source":"RHSA-2021:2034"},{"ecosystem":"Red Hat:enterprise_linux:8::appstream","fixed":["0:6.0.9-3.module+el8.4.0+10984+ed187465"],"introduced":["0"],"last_affected":[],"package":"redis-debugsource","purl":"pkg:rpm/redhat/redis-debugsource","source":"RHSA-2021:2034"},{"ecosystem":"Red Hat:enterprise_linux:8::appstream","fixed":["0:6.0.9-3.module+el8.4.0+10984+ed187465"],"introduced":["0"],"last_affected":[],"package":"redis-devel","purl":"pkg:rpm/redhat/redis-devel","source":"RHSA-2021:2034"},{"ecosystem":"Red Hat:enterprise_linux:8::appstream","fixed":["0:6.0.9-3.module+el8.4.0+10984+ed187465"],"introduced":["0"],"last_affected":[],"package":"redis-doc","purl":"pkg:rpm/redhat/redis-doc","source":"RHSA-2021:2034"},{"ecosystem":"Rocky Linux:8","fixed":["0:6.0.9-3.module+el8.4.0+395+8d498eeb"],"introduced":["0"],"last_affected":[],"package":"redis","purl":"pkg:rpm/rocky-linux/redis?distro=rocky-linux-8-4-legacy\u0026epoch=0","source":"RLSA-2021:2034"}],"prev":{"headline":"Insecure Deserialization of untrusted data in rmccue/requests","id":"CVE-2021-29476"},"products":["redis"],"published":"2021-05-04","related":[{"cvss_score":9.8,"headline":"PHP-CGI OS Command Injection","id":"CVE-2024-4577","kev_date_added":"2024-06-12","published":"2024-06-09"},{"cvss_score":9.8,"headline":"Grafana Authentication Bypass","id":"CVE-2021-39226","kev_date_added":"2022-08-25","published":"2021-10-05"},{"cvss_score":9.8,"headline":"VMware ESXi and Horizon DaaS OpenSLP Heap-Based Buffer Overflow","id":"CVE-2019-5544","kev_date_added":"2021-11-03","published":"2019-12-06"},{"cvss_score":9.6,"headline":"Google Chromium V8 Type Confusion","id":"CVE-2024-4947","kev_date_added":"2024-05-20","published":"2024-05-15"},{"cvss_score":9.6,"headline":"Google Chromium Visuals Use-After-Free","id":"CVE-2024-4671","kev_date_added":"2024-05-13","published":"2024-05-09"},{"cvss_score":9.6,"headline":"Google Chromium Mojo Insufficient Data Validation","id":"CVE-2022-3075","kev_date_added":"2022-09-08","published":"2022-09-26"},{"cvss_score":9.6,"headline":"Google Chromium Indexed DB API Use-After-Free","id":"CVE-2021-30633","kev_date_added":"2021-11-03","published":"2021-10-08"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Red Hat","prefix":"RHSA"},{"class":"attribution","licence":"BSD","name":"Rocky Linux","prefix":"RLSA"},{"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 STRALGO LCS command allows heap corruption and potential remote code execution.","url":"https://insights.sbomify.com/CVE-2021-29477/"}
