Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-32765 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. 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-2021-32765/ (Markdown: https://insights.sbomify.com/CVE-2021-32765/index.md)","id":"CVE-2021-32765","markdown":"https://insights.sbomify.com/CVE-2021-32765/index.md","name":"CVE-2021-32765","record":{"aliases":["DEBIAN-CVE-2021-32765","GHSA-hfm9-39pp-55p2","MGASA-2021-0562","OESA-2021-1390","UBUNTU-CVE-2021-32765","openSUSE-SU-2021:1536-1","openSUSE-SU-2021:1550-1","openSUSE-SU-2024:11561-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Redis client library","requires_auth":"low_privilege","summary":"An integer overflow in Hiredis when parsing multi-bulk replies can lead to buffer overflow, allowing attackers to execute code or cause denial of service.","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":"management_services_for_element_software_and_netapp_hci","vendor":"netapp"},{"product":"hiredis","vendor":"redis"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/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":"Hiredis is a minimalistic C client library for the Redis database. In affected versions Hiredis is vulnurable to integer overflow if provided maliciously crafted or corrupted `RESP` `mult-bulk` protocol data. When parsing `multi-bulk` (array-like) replies, hiredis fails to check if `count * sizeof(redisReply*)` can be represented in `SIZE_MAX`. If it can not, and the `calloc()` call doesn't itself make this check, it would result in a short allocation and subsequent buffer overflow. Users of hiredis who are unable to update may set the [maxelements](https://github.com/redis/hiredis#reader-max-array-elements) context option to a value small enough that no overflow is possible.","ecosystems":["SUSE:Package Hub 15 SP2","SUSE:Package Hub 15 SP3","openSUSE:Leap 15.2","openSUSE:Leap 15.3","openSUSE:Tumbleweed"],"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 to Buffer Overflow in Hiredis","id":"CVE-2021-32765","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux"],"type":"integer_overflow","year":"2021"},"n_packages":5,"n_references":6,"next":{"headline":"Nextcloud Text app can disclose existence of folders in \"File Drop\" link share","id":"CVE-2021-32766"},"packages":[{"ecosystem":"SUSE:Package Hub 15 SP2","fixed":["0.13.3-bp152.4.3.1"],"introduced":["0"],"last_affected":[],"package":"hiredis","purl":"pkg:rpm/suse/hiredis\u0026distro=SUSE%20Package%20Hub%2015%20SP2","source":"openSUSE-SU-2021:1550-1"},{"ecosystem":"SUSE:Package Hub 15 SP3","fixed":["0.13.3-bp153.2.3.1"],"introduced":["0"],"last_affected":[],"package":"hiredis","purl":"pkg:rpm/suse/hiredis\u0026distro=SUSE%20Package%20Hub%2015%20SP3","source":"openSUSE-SU-2021:1536-1"},{"ecosystem":"openSUSE:Leap 15.2","fixed":["0.13.3-bp153.2.3.1"],"introduced":["0"],"last_affected":[],"package":"hiredis","purl":"pkg:rpm/opensuse/hiredis\u0026distro=openSUSE%20Leap%2015.2","source":"openSUSE-SU-2021:1536-1"},{"ecosystem":"openSUSE:Leap 15.3","fixed":["0.13.3-bp153.2.3.1"],"introduced":["0"],"last_affected":[],"package":"hiredis","purl":"pkg:rpm/opensuse/hiredis\u0026distro=openSUSE%20Leap%2015.3","source":"openSUSE-SU-2021:1536-1"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["1.0.2-1.1"],"introduced":["0"],"last_affected":[],"package":"hiredis","purl":"pkg:rpm/opensuse/hiredis\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:11561-1"}],"prev":{"headline":"YouTube Onebox susceptible to XSS","id":"CVE-2021-32764"},"products":["hiredis"],"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":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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 Hiredis when parsing multi-bulk replies can lead to buffer overflow, allowing attackers to execute code or cause denial of service.","url":"https://insights.sbomify.com/CVE-2021-32765/"}
