An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-3326 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-2021-3326/ (Markdown: https://insights.sbomify.com/CVE-2021-3326/index.md)","id":"CVE-2021-3326","markdown":"https://insights.sbomify.com/CVE-2021-3326/index.md","name":"CVE-2021-3326","record":{"aliases":["CLSA-2026-1777481470","DEBIAN-CVE-2021-3326","GHSA-w279-vhxx-7qx8","OESA-2021-1045","UBUNTU-CVE-2021-3326"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"GNU C Library","requires_auth":"none","summary":"Attackers can cause a denial of service by triggering an assertion failure in glibc's iconv function when processing invalid ISO-2022-JP-3 input.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"m10-1_firmware","vendor":"fujitsu"},{"product":"m10-4_firmware","vendor":"fujitsu"},{"product":"m10-4s_firmware","vendor":"fujitsu"},{"product":"m12-1_firmware","vendor":"fujitsu"},{"product":"m12-2_firmware","vendor":"fujitsu"},{"product":"m12-2s_firmware","vendor":"fujitsu"},{"product":"glibc","vendor":"gnu"},{"product":"e-series_santricity_os_controller","vendor":"netapp"},{"product":"ontap_select_deploy_administration_utility","vendor":"netapp"},{"product":"communications_cloud_native_core_security_edge_protection_proxy","vendor":"oracle"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"}],"description":"The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid input sequences in the ISO-2022-JP-3 encoding, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service.","ecosystems":[],"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":"Denial of service in n/a","id":"CVE-2021-3326","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","gnu:glibc","netapp:e-series_santricity_os_controller","netapp:ontap_select_deploy_administration_utility"],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":8,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-3327"},"packages":[],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2021-3325"},"products":["n/a"],"published":"2021-01-27","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":"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-14","vendors":["n/a"]},"summary":"Attackers can cause a denial of service by triggering an assertion failure in glibc's iconv function when processing invalid ISO-2022-JP-3 input.","url":"https://insights.sbomify.com/CVE-2021-3326/"}
