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-2020-16094 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-2020-16094/ (Markdown: https://insights.sbomify.com/CVE-2020-16094/index.md)","id":"CVE-2020-16094","markdown":"https://insights.sbomify.com/CVE-2020-16094/index.md","name":"CVE-2020-16094","record":{"aliases":["CLEANSTART-2023-AQ06363","DEBIAN-CVE-2020-16094","GHSA-8f6j-9hh3-9c9x","MGASA-2020-0391","UBUNTU-CVE-2020-16094"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Claws Mail client","requires_auth":"none","summary":"A malicious IMAP server can cause Claws Mail to crash via stack exhaustion during folder tree rebuilds, requiring users to upgrade the client.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"claws-mail","vendor":"claws-mail"},{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","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-674","name":"Uncontrolled Recursion"}],"description":"In imap_scan_tree_recursive in Claws Mail through 3.17.6, a malicious IMAP server can trigger stack consumption because of unlimited recursion into subdirectories during a rebuild of the folder tree.","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-2020-16094","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"fedoraproject:fedora","products":["fedoraproject:fedora"],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":4,"next":{"headline":"Cross-site Scripting vulnerability in Kitodo.Presentation","id":"CVE-2020-16095"},"packages":[],"prev":{"headline":"Security feature bypass in n/a","id":"CVE-2020-16093"},"products":["n/a"],"published":"2020-07-28","related":[{"cvss_score":9.8,"headline":"Security feature bypass in n/a","id":"CVE-2020-15917","kev_date_added":null,"published":"2020-07-23"},{"cvss_score":7.3,"headline":"Memory corruption in n/a","id":"CVE-2015-8614","kev_date_added":null,"published":"2016-04-11"},{"cvss_score":7.3,"headline":"Memory corruption in n/a","id":"CVE-2015-8708","kev_date_added":null,"published":"2016-04-11"},{"cvss_score":6.8,"headline":"Security feature bypass in n/a","id":"CVE-2014-2576","kev_date_added":null,"published":"2014-10-15"},{"cvss_score":6.1,"headline":"Open redirect in n/a","id":"CVE-2021-37746","kev_date_added":null,"published":"2021-07-30"},{"cvss_score":5,"headline":"Null dereference in n/a","id":"CVE-2012-4507","kev_date_added":null,"published":"2012-10-22"}],"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 malicious IMAP server can cause Claws Mail to crash via stack exhaustion during folder tree rebuilds, requiring users to upgrade the client.","url":"https://insights.sbomify.com/CVE-2020-16094/"}
