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-2015-2929 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-2015-2929/ (Markdown: https://insights.sbomify.com/CVE-2015-2929/index.md)","id":"CVE-2015-2929","markdown":"https://insights.sbomify.com/CVE-2015-2929/index.md","name":"CVE-2015-2929","record":{"aliases":["DEBIAN-CVE-2015-2929","GHSA-f7jp-x5vp-978r","UBUNTU-CVE-2015-2929"],"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 servers can cause Tor clients to crash via malformed hidden service descriptors, requiring an upgrade to maintain availability.","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":[],"description":"The Hidden Service (HS) client implementation in Tor before 0.2.4.27, 0.2.5.x before 0.2.5.12, and 0.2.6.x before 0.2.6.7 allows remote servers to cause a denial of service (assertion failure and application exit) via a malformed HS descriptor.","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-2015-2929","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-2015-2931"},"packages":[],"prev":{"headline":"Denial of service in Tor","id":"CVE-2015-2928"},"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":"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 servers can cause Tor clients to crash via malformed hidden service descriptors, requiring an upgrade to maintain availability.","url":"https://insights.sbomify.com/CVE-2015-2929/"}
