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-2019-11494 in the wild and no public exploit code.\n\nAffected product: Dovecot Dovecot. 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-2019-11494/ (Markdown: https://insights.sbomify.com/CVE-2019-11494/index.md)","id":"CVE-2019-11494","markdown":"https://insights.sbomify.com/CVE-2019-11494/index.md","name":"CVE-2019-11494","record":{"aliases":["ALPINE-CVE-2019-11494","DEBIAN-CVE-2019-11494","GHSA-gcm9-2h5w-j7x9"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Dovecot IMAP server","requires_auth":"none","summary":"A null pointer dereference in Dovecot's submission-login service causes a crash when a client disconnects prematurely during authentication.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"dovecot","vendor":"dovecot"},{"product":"fedora","vendor":"fedoraproject"},{"product":"leap","vendor":"opensuse"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/AC:L/AV:N/A:H/C:N/I:N/PR:N/S:U/UI:N","version":"3.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In the IMAP Server in Dovecot 2.3.3 through 2.3.5.2, the submission-login service crashes when the client disconnects prematurely during the AUTH command.","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":"Null dereference in n/a","id":"CVE-2019-11494","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"dovecot:dovecot","products":["dovecot:dovecot","fedoraproject:fedora","opensuse:leap"],"type":"null_dereference","year":"2019"},"n_packages":0,"n_references":6,"next":{"headline":"Weak cryptography in n/a","id":"CVE-2019-11495"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2019-11493"},"products":["n/a"],"published":"2019-05-08","related":[{"cvss_score":7.7,"headline":"Auth bypass in OX Dovecot Pro","id":"CVE-2026-24031","kev_date_added":null,"published":"2026-03-27"},{"cvss_score":7.5,"headline":"Denial of service in OX Dovecot Pro","id":"CVE-2025-59032","kev_date_added":null,"published":"2026-03-27"},{"cvss_score":7.5,"headline":"Denial of service in OX Dovecot Pro","id":"CVE-2026-27858","kev_date_added":null,"published":"2026-03-27"},{"cvss_score":7.5,"headline":"Path traversal in n/a","id":"CVE-2021-29157","kev_date_added":null,"published":"2021-06-28"},{"cvss_score":7.5,"headline":"Null dereference in n/a","id":"CVE-2020-10957","kev_date_added":null,"published":"2020-05-18"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2020-7046","kev_date_added":null,"published":"2020-02-12"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"A null pointer dereference in Dovecot's submission-login service causes a crash when a client disconnects prematurely during authentication.","url":"https://insights.sbomify.com/CVE-2019-11494/"}
