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-2015-2689 in the wild and no public exploit code.\n\nAffected product: The Tor Project Tor. 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-2015-2689/ (Markdown: https://insights.sbomify.com/CVE-2015-2689/index.md)","id":"CVE-2015-2689","markdown":"https://insights.sbomify.com/CVE-2015-2689/index.md","name":"CVE-2015-2689","record":{"aliases":["DEBIAN-CVE-2015-2689","GHSA-7r2c-ch3m-w27x","UBUNTU-CVE-2015-2689"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Tor anonymity network","requires_auth":"none","summary":"Remote attackers can cause a denial of service in Tor by sending crafted packets during high DNS load, leading to daemon exit.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"debian","cpe":[{"product":"tor","vendor":"torproject"}],"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-20","name":"Improper Input Validation"}],"description":"Tor before 0.2.4.26 and 0.2.5.x before 0.2.5.11 does not properly handle pending-connection resolve states during periods of high DNS load, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via crafted packets.","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 Tor","id":"CVE-2015-2689","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2015"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2015-2690"},"packages":[],"prev":{"headline":"Denial of service in Tor","id":"CVE-2015-2688"},"products":["Tor"],"published":"2020-01-24","related":[{"cvss_score":8.9,"headline":"Race condition in Tor","id":"CVE-2026-77638","kev_date_added":null,"published":"2026-08-20"},{"cvss_score":7.5,"headline":"Memory corruption in Tor","id":"CVE-2026-77642","kev_date_added":null,"published":"2026-08-20"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2022-33903","kev_date_added":null,"published":"2022-07-17"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2021-38385","kev_date_added":null,"published":"2021-08-30"},{"cvss_score":7.5,"headline":"Security feature bypass in n/a","id":"CVE-2021-34548","kev_date_added":null,"published":"2021-06-29"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2021-34549","kev_date_added":null,"published":"2021-06-29"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2021-34550","kev_date_added":null,"published":"2021-06-29"}],"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":"2024-08-06","vendors":["The Tor Project"]},"summary":"Remote attackers can cause a denial of service in Tor by sending crafted packets during high DNS load, leading to daemon exit.","url":"https://insights.sbomify.com/CVE-2015-2689/"}
