An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of PSF-2018-8 in the wild and no public exploit code.\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/PSF-2018-8/ (Markdown: https://insights.sbomify.com/PSF-2018-8/index.md)","id":"PSF-2018-8","markdown":"https://insights.sbomify.com/PSF-2018-8/index.md","name":"PSF-2018-8","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Python email library","requires_auth":"none","summary":"An attacker can cause a denial of service by sending emails with long headers containing many non-ASCII characters, triggering an infinite loop in the email folding function.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The email folding function enters an infinite loop if a header is longer\nthan the policy maximum line length and contains many non-ASCII characters.\n\nRegression introduced in Python 3.6.4.","ecosystems":[],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Email folding function Denial-of-Service","id":"PSF-2018-8","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2018"},"n_packages":0,"n_references":null,"packages":[],"products":null,"published":"2018-05-16","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"Python Software Foundation","prefix":"PSF"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"An attacker can cause a denial of service by sending emails with long headers containing many non-ASCII characters, triggering an infinite loop in the email folding function.","url":"https://insights.sbomify.com/PSF-2018-8/"}
