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-2016-20013 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2016-20013/ (Markdown: https://insights.sbomify.com/CVE-2016-20013/index.md)","id":"CVE-2016-20013","markdown":"https://insights.sbomify.com/CVE-2016-20013/index.md","name":"CVE-2016-20013","record":{"aliases":["GHSA-7rf5-g36v-wpjh","ROOT-OS-UBUNTU-2204-CVE-2016-20013","UBUNTU-CVE-2016-20013"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux password hashing library","requires_auth":"none","summary":"Attackers can cause denial of service via CPU exhaustion by exploiting quadratic runtime complexity in sha256crypt and sha512crypt password hashing.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"sha256crypt","vendor":"sha256crypt_project"},{"product":"sha512crypt","vendor":"sha512crypt_project"}],"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-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"sha256crypt and sha512crypt through 0.6 allow attackers to cause a denial of service (CPU consumption) because the algorithm's runtime is proportional to the square of the length of the password.","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-2016-20013","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2016"},"n_packages":0,"n_references":3,"next":{"headline":"Information disclosure in n/a","id":"CVE-2016-20014"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2016-20012"},"products":["n/a"],"published":"2022-02-19","related":[],"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":["n/a"]},"summary":"Attackers can cause denial of service via CPU exhaustion by exploiting quadratic runtime complexity in sha256crypt and sha512crypt password hashing.","url":"https://insights.sbomify.com/CVE-2016-20013/"}
