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-2017-18187 in the wild and no public exploit code.\n\nAffected product: Arm Mbed Tls. 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-2017-18187/ (Markdown: https://insights.sbomify.com/CVE-2017-18187/index.md)","id":"CVE-2017-18187","markdown":"https://insights.sbomify.com/CVE-2017-18187/index.md","name":"CVE-2017-18187","record":{"aliases":["ALPINE-CVE-2017-18187","DEBIAN-CVE-2017-18187","GHSA-3g9w-ghrc-hc72","UBUNTU-CVE-2017-18187"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"ARM mbed TLS","requires_auth":"none","summary":"An integer overflow in mbed TLS allows bypassing bounds checks during PSK identity parsing, potentially compromising TLS security.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mbed_tls","vendor":"arm"},{"product":"debian_linux","vendor":"debian"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"In ARM mbed TLS before 2.7.0, there is a bounds-check bypass through an integer overflow in PSK identity parsing in the ssl_parse_client_psk_identity() function in library/ssl_srv.c.","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":"Integer overflow in n/a","id":"CVE-2017-18187","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"arm:mbed_tls","products":["arm:mbed_tls","debian:debian_linux"],"type":"integer_overflow","year":"2017"},"n_packages":0,"n_references":7,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2017-18188"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2017-18186"},"products":["n/a"],"published":"2018-02-14","related":[{"cvss_score":9.8,"headline":"Deserialization in n/a","id":"CVE-2026-34877","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2022-46393","kev_date_added":null,"published":"2022-12-15"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2021-44732","kev_date_added":null,"published":"2021-12-20"},{"cvss_score":9.8,"headline":"Memory corruption in ARM mbed TLS before 1.3.22, before 2.1.10, and before 2.7.0","id":"CVE-2018-0487","kev_date_added":null,"published":"2018-02-13"},{"cvss_score":9.8,"headline":"Memory corruption in ARM mbed TLS before 1.3.22, before 2.1.10, and before 2.7.0","id":"CVE-2018-0488","kev_date_added":null,"published":"2018-02-13"},{"cvss_score":9.1,"headline":"Weak cryptography in n/a","id":"CVE-2026-34872","kev_date_added":null,"published":"2026-04-01"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"An integer overflow in mbed TLS allows bypassing bounds checks during PSK identity parsing, potentially compromising TLS security.","url":"https://insights.sbomify.com/CVE-2017-18187/"}
