An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of openSUSE-SU-2021:0334-1 in the wild and no public exploit code.\n\nAffected product: 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/openSUSE-SU-2021-0334-1/ (Markdown: https://insights.sbomify.com/openSUSE-SU-2021-0334-1/index.md)","id":"openSUSE-SU-2021:0334-1","markdown":"https://insights.sbomify.com/openSUSE-SU-2021-0334-1/index.md","name":"openSUSE-SU-2021:0334-1","record":{"aliases":[],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Tor anonymity network","requires_auth":"none","summary":"An attacker can cause denial of service or bypass security checks in Tor relays due to improper channel and circuit validation.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"This update for tor fixes the following issues:\n\ntor was updated to 0.4.5.6:\n\n* https://lists.torproject.org/pipermail/tor-announce/2021-February/000214.html\n* Introduce a new MetricsPort HTTP interface\n* Support IPv6 in the torrc Address option\n* Add event-tracing library support for USDT and LTTng-UST\n* Try to read N of N bytes on a TLS connection\n\ntor was updated to 0.4.4.7:\n\n* https://blog.torproject.org/node/1990\n* Stop requiring a live consensus for v3 clients and services\n* Re-entry into the network is now denied at the Exit level\n* Fix undefined behavior on our Keccak library\n* Strip '\\r' characters when reading text files on Unix platforms\n* Handle partial SOCKS5 messages correctly\n\n* Check channels+circuits on relays more thoroughly (TROVE-2020-005, boo#1178741)\n\nThis update was imported from the openSUSE:Leap:15.2:Update update project.","ecosystems":["SUSE:Package Hub 15 SP2"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"Security update for tor","id":"openSUSE-SU-2021:0334-1","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2021"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"SUSE:Package Hub 15 SP2","fixed":["0.4.5.6-bp152.2.6.1"],"introduced":["0"],"last_affected":[],"package":"tor","purl":"pkg:rpm/suse/tor\u0026distro=SUSE%20Package%20Hub%2015%20SP2","source":"openSUSE-SU-2021:0334-1"}],"products":null,"published":"2021-02-23","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"An attacker can cause denial of service or bypass security checks in Tor relays due to improper channel and circuit validation.","url":"https://insights.sbomify.com/openSUSE-SU-2021-0334-1/"}
