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-2021-46853 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-46853/ (Markdown: https://insights.sbomify.com/CVE-2021-46853/index.md)","id":"CVE-2021-46853","markdown":"https://insights.sbomify.com/CVE-2021-46853/index.md","name":"CVE-2021-46853","record":{"aliases":["DEBIAN-CVE-2021-46853","GHSA-v9q2-jxcm-rm4c","UBUNTU-CVE-2021-46853"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IMAP client library","requires_auth":"none","summary":"Remote attackers can crash the application by sending LIST or LSUB commands before STARTTLS, affecting users of the Alpine IMAP client library.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"alpine","vendor":"alpine_project"}],"cvss":{"score":5.9,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"}],"description":"Alpine before 2.25 allows remote attackers to cause a denial of service (application crash) when LIST or LSUB is sent before STARTTLS.","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":"Race condition in n/a","id":"CVE-2021-46853","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Information disclosure in n/a","id":"CVE-2021-46854"},"packages":[],"prev":{"headline":"Auth bypass in EMUI","id":"CVE-2021-46852"},"products":["n/a"],"published":"2022-11-03","related":[{"cvss_score":7.5,"headline":"URL access filters bypass in Alpine","id":"CVE-2022-23553","kev_date_added":null,"published":"2022-12-28"},{"cvss_score":7.5,"headline":"Security feature bypass in n/a","id":"CVE-2020-14929","kev_date_added":null,"published":"2020-06-19"},{"cvss_score":6.5,"headline":"Authentication bypass in Alpine","id":"CVE-2022-23554","kev_date_added":null,"published":"2022-12-28"},{"cvss_score":5.9,"headline":"Security feature bypass in n/a","id":"CVE-2021-38370","kev_date_added":null,"published":"2021-08-10"}],"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":"2025-05-05","vendors":["n/a"]},"summary":"Remote attackers can crash the application by sending LIST or LSUB commands before STARTTLS, affecting users of the Alpine IMAP client library.","url":"https://insights.sbomify.com/CVE-2021-46853/"}
