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-2011-0490 in the wild and no public exploit code.\n\nAffected product: Tor 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-2011-0490/ (Markdown: https://insights.sbomify.com/CVE-2011-0490/index.md)","id":"CVE-2011-0490","markdown":"https://insights.sbomify.com/CVE-2011-0490/index.md","name":"CVE-2011-0490","record":{"aliases":["DEBIAN-CVE-2011-0490","GHSA-xwc2-2xh3-v7qg"],"analysis":{"component_type":"server_software","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 crash the Tor daemon by triggering specific log messages, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"tor","vendor":"tor"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[],"description":"Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha makes calls to Libevent within Libevent log handlers, which might allow remote attackers to cause a denial of service (daemon crash) via vectors that trigger certain log messages.","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-2011-0490","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"tor:tor","products":["tor:tor"],"type":"denial_of_service","year":"2011"},"n_packages":0,"n_references":6,"next":{"headline":"Integer overflow in n/a","id":"CVE-2011-0491"},"packages":[],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2011-0489"},"products":["n/a"],"published":"2011-01-19","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2010-1676","kev_date_added":null,"published":"2010-12-22"},{"cvss_score":10,"headline":"Tor before 0.2.0.34 treats incomplete IPv4 addresses as valid, which has unknown impact and attack vectors related to \"Spec conformance,\" as","id":"CVE-2009-0939","kev_date_added":null,"published":"2009-03-18"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2009-0414","kev_date_added":null,"published":"2009-02-03"},{"cvss_score":9.3,"headline":"Information disclosure in n/a","id":"CVE-2008-5398","kev_date_added":null,"published":"2008-12-09"},{"cvss_score":7.6,"headline":"Memory corruption in n/a","id":"CVE-2011-2778","kev_date_added":null,"published":"2011-12-23"},{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2006-3409","kev_date_added":null,"published":"2006-07-07"},{"cvss_score":7.2,"headline":"Privilege escalation in n/a","id":"CVE-2008-5397","kev_date_added":null,"published":"2008-12-09"}],"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":["n/a"]},"summary":"Remote attackers can crash the Tor daemon by triggering specific log messages, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2011-0490/"}
